Practice problem
Find the inverse of the function: f(x)=−4+9x3f(x)= \dfrac {-4+9x}{3}f(x)=3−4+9x
f−1(x)=13x+43f^{-1}(x) = \dfrac{1}{3}x +\dfrac{4}{3}f−1(x)=31x+34
f−1(x)=13x+49f^{-1}(x) = \dfrac{1}{3}x +\dfrac{4}{9}f−1(x)=31x+94
f−1(x)=19x+49f^{-1}(x) = \dfrac{1}{9}x +\dfrac{4}{9}f−1(x)=91x+94
f−1(x)=13x+19f^{-1}(x) = \dfrac{1}{3}x +\dfrac{1}{9}f−1(x)=31x+91
Type a concept, like “slope” or “photosynthesis”.
