Practice problem
Find the inverse of the function: f(x)=−2x+73f(x)= \dfrac{-2x+7}{3}f(x)=3−2x+7
f−1(x)=32+72xf^{-1}(x) = \dfrac{3}{2} + \dfrac{7}{2}xf−1(x)=23+27x
f−1(x)=72−32xf^{-1}(x) = \dfrac{7}{2} - \dfrac{3}{2}xf−1(x)=27−23x
f−1(x)=23+72xf^{-1}(x) = \dfrac{2}{3} + \dfrac{7}{2}xf−1(x)=32+27x
f−1(x)=32+7xf^{-1}(x) = \dfrac{3}{2} + 7xf−1(x)=23+7x
Type a concept, like “slope” or “photosynthesis”.
