End behavior
I have to find the zeros, vertical assymptotes and end behavior of the functions, how do i find the end behavior?

a) f(x)=x-7
vertical asymptote at x=0
there are no zeros since it does not cross the x-axis

b)g(x)=4/x8
ver. asym. at x=0
there are no zeros since it does not cross the x-axis

c)h(x)=2*3x+2

$f(-1) = (-1)^{-7} = -1$

So that means...

I'm not certain what "end behavior" is either. Can you find the definition in your text?

Re: End behavior
The "end behavior" is the "behavior" or what happens to the function in the limit as x goes to infinity or negative infinity.
