A parabola has a vertex at (-1.5,12.5) and passes through (0,8). Solve for "a" and write the equation in vertex form.

Formula: f(x) = a(x - h)² + k

• y = -1.5(12.5 - 8)²

• y = 2(x + 0)² + 8

• y = -2(x + 1.5)² + 12.5

• y = 8(x + 1.5)² - 12.5

• None of the above

Use the vertex form to write the equation of the parabola.

• y = -(x - 2)² + 5

• y = -3(x - 2)² + 5

• y = -3(x + 2)² + 5

• y = -3(x + 2)² - 5
