**Reiny**, Saturday, January 19, 2013 at 11:37pmYou should have an idea what

f(x) = 3^x looks like

its domain is any real number of x

the range is y>0

so you have f(x) = 3^x - 4 , which just drops the curve down 4 units

the domain is still x ∈ R , the domain is y > -4

if you meant: f(x) = 3^(x-4) , then y = 3^x was shifted to the right 4 units.

domain still x ∈ R, range : y > 0
