Answer:
y(x) = (-1/18)(x+3)(x+2)(x-1)(x-3)
Step-by-step explanation:
There are 4 x-intercepts: -3, -2, 1, 3
So y(x) = C(x+3)(x+2)(x-1)(x-3)
At x = 0, y-intercept is -1
so -1 = C*3*2*(-1)*(-3) = 18C,
C = -1/18
Then y(x) = (-1/18)(x+3)(x+2)(x-1)(x-3)

perimeter = semicircle (x2) + parallelogram side (x2)
= 1/2 π 12 (x2) + 15 (x2)
= 37.7 + 30
= 67.7
