We are adding twice what we added to the previous number. Each time we double what we're adding.
Such a prism would have 2 14x7 faces, 2 7x28 faces, and 2 28x14 faces. Then, the surface area of the prism would be
2 * 14 * 7 + 2 * 7 * 28 + 2 * 28 * 14 = 1372
Given the endpoints of our diameter, we can use the distance formula to find the distance between the points.
Distance Formula:
(
and 
are the x-values of the coordinates and 
and 
are the y-values of the coordinates)
Inserting our values into the distance formula we can find the length of the diameter:
The diameter of our circle is 6, or choice C.
The function is invertible on either side of the vertex. There are many possible answers. Ones that include the vertex are ...
x ≥ 3
or
x ≤ 3
