Question

What is the effect on the graph of f(x) = x2 when it is transformed to

h(x) = 322 +12?
O A. The graph of f(x) is vertically compressed by a factor of 5 and
shifted 12 units to the left.
O B. The graph of f(x) is horizontally stretched by a factor of 5 and
shifted 12 units to the left.
O C. The graph of f(x) is horizontally compressed by a factor of 5 and
shifted 12 units up.
OD. The graph of f(x) is vertically compressed by a factor of 5 and
shifted 12 units up.

Answer 1

Explanation:

The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12
