If h moves the graph left or right,

(moves left)

(moves right)

If h moves the graph up or down,

(moves up)

(moves down)

Answer:
A.
Explanation:
4 goes up 2 to 6. 6 goes up 3 to 9. 9 goes up 4 to 13. Therefore, you can expect 13 to go up 5 to 18, and 18 to go up by 6 to 24.
Translate it up, translate it down, translate it to the right, translate it to the left, stretch it vertically, stretch it horizontally
For dA in a circle, the r value varies , but its area is still rdrd(theta) but r (and theta) differs depending where the region is
and the regions could be any regions as long as it is a continuous region
