Prompt

The function

f

is defined by

f (x) = a (3. 1^{x} + 3. 1^{b})

where

a

and

b

are integer constants and

0 < a < b

. The functions

g

and

h

are equivalent to function

f

, where

k

and

m

are constants. Which of the following equations displays the

y

-coordinate of the

y

-intercept of the graph of

y = f (x)

in the

x y

-plane as a constant or coefficient?

I.

g (x) = a (3. 1^{x} + k)

II.

h (x) = a (3.1)^{x} + m

I only

A

II only

B

I and II

C

Neither I nor II
