Linear and Exponential Function Transformations:

Two exponential functions, f and g, are shown in the figure below, where g is a transformation of f.

Which of the rules given below shows the transformation of f?

Answer 1

The answer if g(x) = f(x)  + 2.

Answer 2

For this case we observe that both functions have the same behavior.
The cut point of f (x) with the y axis is:
(0, 4)
The cut point of g (x) with the y axis is:
(0, 2)
Therefore the transformation applied to g (x) is:
g (x) = f (x) - 2
Answer:
g (x) = f (x) - 2
