Practice problem
If f(x)=2x−73f(x)= \dfrac{2x-7}{3}f(x)=32x−7, find f−1(x)f^{-1}(x)f−1(x).
f−1(x)=32x+72f^{-1}(x)= \dfrac {3}{2}x + \dfrac{7}{2}f−1(x)=23x+27
f−1(x)=x+73f^{-1}(x)= x + \dfrac{7}{3}f−1(x)=x+37
f−1(x)=72x+32f^{-1}(x)= \dfrac {7}{2}x + \dfrac{3}{2}f−1(x)=27x+23
f−1(x)=73x+32f^{-1}(x)= \dfrac {7}{3}x + \dfrac{3}{2}f−1(x)=37x+23
Type a concept, like “slope” or “photosynthesis”.
