What is the effect on the graph of f(x) = x2 when it is transformed to h(x) = 2x2 – 9?
-
A. The graph of f(x) is vertically compressed by a factor of 6 and
shifted 9 units to the right.
B. The graph of f(x) is horizontally compressed by a factor of 6 and
shifted 9 units down.
C. The graph of f(x) is vertically compressed by a factor of 6 and
shifted 9 units down.
D. The graph of f(x) is horizontally stretched by a factor of 6 and
shifted 9 units to the right.
