Finding Constants and Integrating Functions

The video tutorial explains how to find the value of f(4) given f'(x) = 9x^2 + 10x and f(1) = 7. It involves integrating the derivative to find f(x) + C, applying the power rule of integration, simplifying the expression, solving for the constant C using the given f(1) = 7, and finally calculating f(4) by substituting the values into the derived function.

What is the given derivative function f'(x)?

• 9x^2 + 10x

• 9x^3 + 10x^2

• 3x^3 + 5x^2
