I'm having a hard time understanding these
Let g(x) = 3(x+2)^2 + 4
a. Graph y=gx without a calculator (how do I graph it???, we haven't learned this yet)
b. Why is it not invertible?
c. Let f(x) = 3(x+2)^2 + 4, x>=-2, why is f invertible?
d. What is the domain of f^-1
e. Determine rule for f^-1 (x)
