Which graph represents the parent function of y=(x+2)(x-2)

Find the roots of the polynomial function f(x) = x^3 + 2x^2 + x

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
