Practice problem
What is the inverse function of f(x)=2x+1f(x) = 2x +1f(x)=2x+1?
f−1(x)=−2x−1f^{-1}(x) = -2x - 1f−1(x)=−2x−1
f−1(x)=−12x−12f^{-1}(x) = -\frac12 x - \frac12f−1(x)=−21x−21
f−1(x)=12x−12f^{-1}(x) = \frac12 x - \frac12f−1(x)=21x−21
f−1(x)=−12x+12f^{-1}(x) = -\frac12 x + \frac12f−1(x)=−21x+21
f−1(x)=12x+12f^{-1}(x) = \frac12 x + \frac12f−1(x)=21x+21
Type a concept, like “slope” or “photosynthesis”.
