3. Given the function y = 5x – 2: (a) Find the difference quotient Ay/Ax. What type of function is it? (b) Since the expression

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?
