Suppose that fis a function given asf(x)=-x-72.a. Write and simplify the difference quotient, f(x+h)-f(x)h. Note that you may need to"rationalize the numerator" as part of the simplification process.f(x+h)-f(x)h=c. The derivative of the function, f'(x),is the limitof the difference quotient ash approaches zero.f'(x)=limh0f(x+h)-f(x)h=
