You think well. Can you tell us why you think C?

I think it could be C :D

lena772 · Answer

Well I simply plugged in the number to the equation.. f(1)=1 Aand f(2)=0.333333(recurring) the function of x is the value of y when x equals that number. So if you plot 1,1 there are 2 lines that are there, but when you plot 1, 0.33333 there is only one line and thats C

Actually when you plot 1,1 there is still only one line but i did the second one just to make sure :)

Good job. You could also plug in x=0 to see what it equals, and knowing it's an exponent of -x, eliminate the incorrect graph that also passes through that point.

"Well I simply plugged in the number to the equation.. f(1)=1"  that works fine though :) but there's only one line passing through (1,1) not two.

Yea I realized that after. I did f(2) just to make sure. :)
