The turning point of the function, f(x) = -2(x + 3)² + 7, can be described as:

• (-3, 7) and is a maximum point

• (-3, 7) and is a minimum point

• (3, 7) and is a maximum point

• (3, 7) and is a minimum point

Write the equation of the parabola shown in vertex form.

Write the equation of the parabola that has x-intercepts of (-2, 0) and (6, 0) and passes through the point (7, 27) in root form.

Write a quadratic equation given the x intercepts and one other point.

Step 1: Write the factors.

The intercepts of this function are (6, 0) and (8, 0). Write the factors.
