Match the graph to one of the exponential functions .

The second possible answer is the correct one.

Step-by-step explanation:

The second possible answer is the correct one.  As x increases, 4^x increases exponentially.  However, in this case there's a negative sign in front of 4^x, so we know that the graph follows an exponential trajectory downward.  Also note that 4^0 = 1, so 1 - 4^x = 0 at x = 0.

i would say c is the best answer, hope it's right!

good luck! =)
