Write a polynomial function with zeros at -5,1/2, 3 and a y intercept of 15.

For starters, write three factors which would give you the x-intercepts of -5, 1/2, and 3, those being (x+5), (x-1/2), and (x-3). Now, multiply the factors and set y equal to them, giving you . Now, find your y-intercept,  and subtract it from your desired y-intercept, 15-7.5=7.5. Now add this to your equation,  making your answer .

X= -5because this is a single step equation so you would just have to divide -16 both sides for x to equal your solution
