I need help with these pre-calculus problems?

Question

f(x)=4e^(x)-7
and
f(x)=-7e^(-x+4)+4

finding the domain,range,x-intercepts,y-int.,horizantal asymptote,vertical asym.,up or down constant, and if its continuous or discrete

and how do i graph them

Answer 1

This seems like a lot of info that you should know already how to do. As for graphing, their domains are from -inf to + inf, and they will range from -7 to infinity for the first, and +4 to -infinity for the second. As for graphing them, just know that exp(0)=1, exp(1)=2.82,exp(2.3)=10 for some bench-mark point.
