Practice problem
Find the inverse of the function: f(x)=−2x+7f(x) = -2x+7f(x)=−2x+7
f−1(x)=−12x+72f^{-1}(x) = -\dfrac{1}{2} x + \dfrac {7}{2}f−1(x)=−21x+27
f−1(x)=2x+72f^{-1}(x) = 2 x + \dfrac {7}{2}f−1(x)=2x+27
f−1(x)=12x+72f^{-1}(x) = \dfrac{1}{2} x + \dfrac {7}{2}f−1(x)=21x+27
f−1(x)=−12x−27f^{-1}(x) = -\dfrac{1}{2} x - \dfrac {2}{7}f−1(x)=−21x−72
Type a concept, like “slope” or “photosynthesis”.
