Practice problem
Find the inverse of the function. f(x)=9x−1f(x)=9x-1f(x)=9x−1
f−1(x)=±x+19f^{-1}(x)=\pm\frac{x+1}{9}f−1(x)=±9x+1
f−1(x)=x9+1f^{-1}(x)=\frac x9+1f−1(x)=9x+1
f−1(x)=9(x+1)f^{-1}(x)=9(x+1)f−1(x)=9(x+1)
f−1(x)=x+19f^{-1}(x)=\frac{x+1}{9}f−1(x)=9x+1
Type a concept, like “slope” or “photosynthesis”.
