Determine how many, what type, and find the roots for f(x) = x4 + 21x2 − 100. determine how many, what type, and find the roots for f(x) = x3 − 5x2 − 25x + 125. the following graph shows a seventh-degree polynomial: graph of a polynomial that touches the x axis at negative 5, crosses the x axis at negative 1, crosses the y axis at negative 2, crosses the x axis at 4, and crosses the x axis at 7. part 1: list the polynomial’s zeroes with possible multiplicities. part 2: write a possible factored form of the seventh degree function. without plotting any points other than intercepts, draw a possible graph of the following polynomial: f(x) = (x + 8)3(x + 6)2(x + 2)(x − 1)3(x − 3)4(x − 6).
