Please solve on paper with so I can follow along and understand it

6.2 1. Given the function y = 4x2 + 9: (a) Find the difference quotient as a function of x and Ax. (Use x in lieu of xo.) (b) Find the derivative dy/dx. (c) Find f'(3) and f'(4). 2. Given the function y = 5x* - 4x: (@) Find the difference quotient as a function of x and AX. (b) Find the derivative dy/dx. (c) Find f'(2) and f'(3). 3. Given the function y = 5x - 2: (a) Find the difference quotient Ay/ Ax, What type of function is it? (b) Since the expression Ax does not appear in the function Ay/Ax in part (a), does it make any difference to the value of Ay/Ax whether Ax is large or small? Conse- quently, what is the limit of the difference quotient as Ax approaches zero? mparafive-Static Analysis erivative and the Slope of a Curve
