Practice problem
Find the inverse function.
f(x)=x+9−4f\left(x\right)=\sqrt{x+9}-4f(x)=x+9−4
f−1(x)=x+5f^{-1}(x)=x+5f−1(x)=x+5
f−1(x)=x2+8x+16f^{-1}(x)=x^2+8x+16f−1(x)=x2+8x+16
f−1(x)=x2+8x+7f^{-1}(x)=x^2+8x+7f−1(x)=x2+8x+7
f−1(x)=x2+7x+8f^{-1}(x)=x^2+7x+8f−1(x)=x2+7x+8
Type a concept, like “slope” or “photosynthesis”.
