Practice problem
If f(x)=log9(x3+17)f(x)= \log_{9}(x^3+17)f(x)=log9(x3+17), find the inverse of f(x)f(x)f(x).
f−1(x)=9x−173f^{-1}(x) = \sqrt[3]{9x - 17}f−1(x)=39x−17
f−1(x)=17x−93f^{-1}(x) = \sqrt[3]{17^x - 9}f−1(x)=317x−9
f−1(x)=9x−173f^{-1}(x) = \sqrt[3]{9^x - 17}f−1(x)=39x−17
f−1(x)=9x−17f^{-1}(x) = \sqrt{9^x - 17}f−1(x)=9x−17
Type a concept, like “slope” or “photosynthesis”.
