(-3, -1)
(-3, 1)
(3, 1)
(3, -1)

Last Option

(3, -1)

Step-by-step explanation:

We have the following quadratic function:

By definition for a quadratic function in the form:

the vertex of the function is always the point (h, k)

Note that for this case the values of h, a, and k are:

Therefore the vertex of the function is the point

(3, -1)

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set
