Question 529116:
What I have to do here is find the y-intercept, the zeros, domain, x-intercept, and end behavior.
I know that you have to simplify the factors, which would be

I just don't know what else to do to find the rest. I know that to find the y-intercept you have to set the x to zero, correct? And to find the x-intercept you set the whole equation to zero.

Question 529282: f(x) = (1/3)^x
what would the domain and range of this function be?
I am guessing that there is one asymptote y = 1/3
So only the range has a restriction.
Making the domain (negative infinity , positive infinity) and
Making the range ( 1/3 , positive infinity)
am I correct?
