Use the definition of the derivative to find the derivative of: f(x) = 15x - 14. Part 1: State the definition of the derivative (15(x+h)-14) 15x - 14 f'(x) = lim h Part 2: Using the function given, find the numerator and denominator of the limit given in Part 1 Part 3: Using Part 2, find the derivative by calculating the limit as h approaches
