Question

Prompt

The functions

f

and

g

are defined by the equations shown, where

a

and

b

are integer constants,

a < b

and

b < 0

. If

y = f (x)

and

y = g (x)

are graphed in the

x y

-plane, which of the following equations displays, as a constant or coefficient, the y-coordinate of the y-intercept of the graph of the corresponding function?
I.

f (x) = a (4.2)^{x + b}

II.

g (x) = a (4.2)^{x} + b

I only

II only

I and II

Neither I nor II
