Practice problem
If f(x)=3x+8f(x)= 3x+8f(x)=3x+8, find the inverse function.
f−1(x)=13x−83f^{-1}(x)= \dfrac{1}{3}x-\dfrac{8}{3}f−1(x)=31x−38
f−1(x)=13x+8f^{-1}(x)= \dfrac{1}{3}x+ 8f−1(x)=31x+8
f−1(x)=3x+8f^{-1}(x)= 3x+8f−1(x)=3x+8
f−1(x)=38x+13f^{-1}(x)= \dfrac{3}{8}x+ \dfrac{1}{3}f−1(x)=83x+31
Type a concept, like “slope” or “photosynthesis”.
