(- 3, - 13 ) and (8, 1 )

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Both equations are in vertex form

(8)

y = 5(x + 3)² - 13

with vertex = (h, k) = (- 3, - 13 )

(9)

y = (x - 8)² + 1

with vertex = (h, k) = (8, 1 )

the answer is 375 miles

step-by-step explanation:

f(x) = y

f(-3) = -5
