the function y=4^x has which kind of asymptotes

Question

anonymous · Answer

$$y = 4^{x} $$

This is a exponential function. 

If x = 0 what do you get?

if x = -1 is your answer still positive?

Look at this graph and tell me what asymptote you think there is.|dw:1375414612898:dw|

anonymous · Answer

both

anonymous · Answer

y=0 and some random x=...

anonymous · Answer

so vertical & horizontal is most likely the answer you're looking for

anonymous · Answer

is it both vertical and horizontal

anonymous · Answer

No, the line crosses the y axis but it never goes below the x axis. What does that mean?

anonymous · Answer

If the line did not cross the y axis than it yes it would be both but alas it does.

anonymous · Answer

horizontal

anonymous · Answer

Can you give me a y = ? answer

anonymous · Answer

thats all they gave me was that function

anonymous · Answer

Well when does y = 0 at the x axis?

anonymous · Answer

I wanted to see you say all the time ....haha @holtsgirl ... so 

wouldn't your asymptote be y = 0.

anonymous · Answer

In summary exponential functions have a horizontal asymptote at y = 0 . Done.
