Let f(x) = 1 - 5 x^2 . If h \neq 0 , then the difference quotient
can be simplified as
\frac{f(x + h) - f(x)}{h} = Ah + Bx + C,
where A , B , and C are
constants. (Note: It's possible for one or more of these
constants to be 0.) Find the constants.

Use the simplified expression to find

Finally, find each of the following:
