Direct link to loumast17's post End behavior is looking a. WebMath. Posted 7 years ago. How do I find the answer like this. Using the Factor Theorem, the equation for the graphed polynomial is: The Factor Theorem states that a polynomial function with roots(also called zeros) is given by the following rule. WebPolynomial functions are functions consisting of numbers and some power of x, e.g. Linear equations are degree 1 (the exponent on the variable = 1). When we are given the graph of a polynomial, we can deduce what its zeros are, which helps us determine a few factors the polynomial's equation must include. We can see the difference between local and global extrema below. A polynomial labeled p is graphed on an x y coordinate plane. %. Solution for Write an equation for the polynomial graphed below with degree 4. graph is attached as jpg. if you can figure that out. On the graph of a function, the roots are the values of x for which it crosses the x-axis, hence they are given as follows: When x = 0, y = -3, hence the leading coefficient a is found as follows: More can be learned about the Factor Theorem at brainly.com/question/24380382, This site is using cookies under cookie policy . x, equals, start color #01a995, k, end color #01a995, f, left parenthesis, x, right parenthesis, equals, 0, start color #01a995, k, end color #01a995, left parenthesis, start color #01a995, k, end color #01a995, comma, 0, right parenthesis, y, equals, f, left parenthesis, x, right parenthesis, x, minus, start color #01a995, k, end color #01a995, f, left parenthesis, x, right parenthesis, g, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 3, right parenthesis, left parenthesis, x, plus, 2, right parenthesis, g, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 3, right parenthesis, left parenthesis, x, minus, left parenthesis, minus, 2, right parenthesis, right parenthesis, g, left parenthesis, x, right parenthesis, left parenthesis, x, minus, start color #01a995, 3, end color #01a995, right parenthesis, left parenthesis, x, minus, left parenthesis, start color #01a995, minus, 2, end color #01a995, right parenthesis, right parenthesis, g, left parenthesis, x, right parenthesis, equals, 0, x, equals, start color #01a995, 3, end color #01a995, x, equals, start color #01a995, minus, 2, end color #01a995, start color #01a995, 3, end color #01a995, start color #01a995, minus, 2, end color #01a995, y, equals, g, left parenthesis, x, right parenthesis, 0, equals, g, left parenthesis, x, right parenthesis, left parenthesis, start color #01a995, 3, end color #01a995, comma, 0, right parenthesis, left parenthesis, start color #01a995, minus, 2, end color #01a995, comma, 0, right parenthesis, f, left parenthesis, x, right parenthesis, equals, left parenthesis, x, plus, 4, right parenthesis, left parenthesis, x, minus, 7, right parenthesis, left parenthesis, minus, 4, comma, 0, right parenthesis, left parenthesis, 7, comma, 0, right parenthesis, left parenthesis, 4, comma, 0, right parenthesis, left parenthesis, minus, 7, comma, 0, right parenthesis, left parenthesis, 2, comma, 0, right parenthesis, 2, slash, 3, space, start text, p, i, end text, h, left parenthesis, x, right parenthesis, h, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 1, right parenthesis, left parenthesis, x, plus, 3, right parenthesis, h, left parenthesis, x, right parenthesis, equals, left parenthesis, x, plus, 1, right parenthesis, left parenthesis, x, minus, 3, right parenthesis, h, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 1, right parenthesis, left parenthesis, x, minus, 3, right parenthesis, h, left parenthesis, x, right parenthesis, equals, left parenthesis, x, plus, 1, right parenthesis, left parenthesis, x, plus, 3, right parenthesis, f, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 1, right parenthesis, left parenthesis, x, minus, 4, right parenthesis, start superscript, start color #aa87ff, 2, end color #aa87ff, end superscript, start color #aa87ff, 2, end color #aa87ff, left parenthesis, x, minus, 4, right parenthesis, f, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 1, right parenthesis, start color #aa87ff, left parenthesis, x, minus, 4, right parenthesis, left parenthesis, x, minus, 4, right parenthesis, end color #aa87ff, f, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 3, right parenthesis, left parenthesis, x, minus, 1, right parenthesis, cubed, g, left parenthesis, x, right parenthesis, equals, left parenthesis, x, plus, 1, right parenthesis, cubed, left parenthesis, 2, x, plus, 1, right parenthesis, squared, minus, start fraction, 1, divided by, 2, end fraction, start fraction, 1, divided by, 2, end fraction, f, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 1, right parenthesis, left parenthesis, x, minus, 4, right parenthesis, squared, g, left parenthesis, x, right parenthesis, equals, left parenthesis, x, minus, 1, right parenthesis, squared, left parenthesis, x, minus, 4, right parenthesis, h, left parenthesis, x, right parenthesis, equals, x, squared, left parenthesis, x, minus, 3, right parenthesis, f, left parenthesis, x, right parenthesis, equals, minus, x, cubed, plus, 4, x, squared, minus, 4, x.
