when graphed, which function has a horizontal asymptote at 4?

a. f(x)=2x-4

b. f(x)=2(3^x)+4

c. f(x)=-3x+4

d. f(x)=3(2^x)-4

B.

Step-by-step explanation:

We have to find that which graph has horizontal asymptote at 4

We know that to find the horizontal asymptote , we simply evaluate the limit of the function as it approaches to infinity or it approaches to negative infinity.

A.

Limit of function does not exits, so function have not horizontal asymptote.

B.

Because

Hence, function have horizontal asymptote at 4.

C.

Hence, function have not horizontal asymptote.

D.

Because

Hence, function have horizontal asymptote at -4.

Therefore, option B is true.

true
