Given the vertex (3, -7) and the point (2,-6). Write the vertex form of the
equation.

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                        f(x) = a(x - h)² + k

the vertex is (3, -7)  ⇒   h = 3,  k = -7

so:

     f(x) = a(x - 3)² - 7

The parabola goes through the point (2, -6) ⇒   x=2,  f(x)=-6

-6 = a(2 - 3)²  - 7

-6 = a(-1)²  - 7

+7           +7

1  = a

It means the equation of the parabola in vertex form:

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

it will be a cylinder. with a diameter of 8 and 4 single pieces high
