Beyond the Answer
To find \( h(x) \), we simply add the two functions: \( h(x) = f(x) + g(x) = (9x^2 - 5) + (5x^2 + 10) = 14x^2 + 5 \). Now, let's differentiate \( h(x) \) to find \( h'(x) \): Using the power rule, we have: \( h'(x) = \frac{d}{dx}(14x^2 + 5) = 28x \). Thus, \( h(x) = 14x^2 + 5 \) and \( h'(x) = 28x \).
