Q. Let h(x)=7−x−2x5 and let f be the inverse function of h. Notice that h(−1)=10.f′(10)=
Use Inverse Function Derivative Formula: To find f′(10), we need to use the formula for the derivative of the inverse function: f′(x)=h′(f(x))1.
Find Derivative of h(x): First, we need to find h′(x) which is the derivative of h(x)=7−x−2x5.h′(x)=−1−10x4.
Calculate h'(\-1): Since h(\-1) = 10, we need to find h'(\-1) to use in our formula.$h'((-1\)) = (-1\) - \(10\)((-1\))^{\(4\)} = (-1\) - \(10\)(\(1\)) = (-1\) - \(10\) = (-11\).
Find \(f'(10)\): Now we can find \(f'(10)\) using the formula.\(\newline\)\(f'(10) = \frac{1}{h'(f(10))} = \frac{1}{h'(-1)} = \frac{1}{-11}.\)
Final Result: So, \(f^{\prime}(10) = -\frac{1}{11}.\)
