Answer
a. $x=-3$, even multiplicity, $x=2$, even multiplicity
b. $y=-(x+3)^2(x-2)^2$
c. $y=-36$
Work Step by Step
a. zeros: $x=-3$, even multiplicity, $x=2$, even multiplicity
b. We can write the equation as $y=-(x+3)^2(x-2)^2$
c. The y-intercept can be found as $y=-36$ from the above equation by letting $x=0$, or by reading from the given graph.
