Let f (x) = 3^x.

Which function represents a transformation of f (x) by a vertical stretch with factor 6?

g (x) = 1/6 ⋅ 3^x

g (x) = 3^1/6x

g (x) = 3^6x

g (x) = 6 ⋅ 3^x

Let f (x) = 5^x.

Let g (x) = 5^x - 7.

Which statement describes the graph of g (x) with respect to the graph of f (x) ?

A. g (x) is translated 7 units left from f (x).

B. g (x) is translated 7 units up from f (x).

C. g (x) is translated 7 units right from f (x).

D. g (x) is translated 7 units down from f (x).
