Answer:
P(x) = -1/2(x -3)²(x +3)
Step-by-step explanation:
When q is a root of the polynomial, (x-q) is a factor. This polynomial will be ...
P(x) = a(x -3)²(x +3)
For x=0, the y-intercept will be ...
P(0) = 27a = -13.5
Then the value of a is ...
a = -13.5/27 = -1/2
The formula for P(x) is ...
P(x) = -1/2(x -3)²(x +3) . . . . . . factored form
P(x) = -0.5x³ +1.5x² +4.5x -13.5 . . . . standard form
