Practice problem
Find the inverse of the function.
f(x)=2x+1f(x)=2x+1f(x)=2x+1
f−1(x)=x−12f^{-1}\left(x\right)=\frac{x-1}{2}f−1(x)=2x−1
f−1(x)=x−21f^{-1}\left(x\right)=\frac{x-2}{1}f−1(x)=1x−2
f−1(x)=2x−1f^{-1}\left(x\right)=\frac{2}{x-1}f−1(x)=x−12
f−1(x)=2−xf^{-1}\left(x\right)=2-xf−1(x)=2−x
Type a concept, like “slope” or “photosynthesis”.
