Question

Write the equation of the parabola that has the vertex at point (-2, -2) and passes through the point (-1, -1)

Answer 1

y = (x+2)²-2

Explanation:

Use the vertex form y = a(x-h)²+k. Plug in the vertex for h and k. Solve for a and you will get 1 for that value. You can check your answers by plugging in both of those points to make sure.
