11. Write an equation for the parabola with vertex (-3, -7) and point (-2,-5).

Step-by-step explanation:

f(x) = a(x - h)² + k      - an equation for the parabola with vertex (h, k)

f(x) = a(x - (-3))² + (-7)      - an equation for the parabola with vertex (-3, -7)

f(x) = a(x + 3)² - 7

The parabola going through point (-2,-5) so if x = -2 then f(x) = -5

- 5 = a(-2 + 3)² - 7

- 5 + 7 = a(1)² - 7 + 7

   2 = 1a

   a = 2

So  an equation for the parabola with vertex (-3, -7) and point (-2,-5)

                             f(x) = 2(x + 3)² - 7
