Practice problem
What is the inverse of the following function? f(x)=2x+87f(x)=\sqrt[7]{2x+8}f(x)=72x+8
f−1(x)=x7+82f^{-1}(x)=\frac{x^{7}+8}{2}f−1(x)=2x7+8
f−1(x)=x17+82f^{-1}(x)=\frac{x^{\frac{1}{7}}+8}{2}f−1(x)=2x71+8
f−1(x)=x7−82f^{-1}(x)=\frac{x^7-8}{2}f−1(x)=2x7−8
f−1(x)=x7−87f^{-1}(x)=\frac{x^{7}-8}{7}f−1(x)=7x7−8
Type a concept, like “slope” or “photosynthesis”.
