@ Question 7 v Note: Your answers should be in simplest form. This may mean that you need to expand, collect, or factor in order to simplify each expression. Suppose that f is a function given as f(z) = /3z 2. Simplify the expression f(z + h). flz+h)= | flo +h) (@) Simplify the difference quotient, 5 f(z +h) f(z) _' ' - Rationalize the numerator in the difference quotient. (If applies, simplify again.) f(z +h) f(=z) _' ' - The derivative of the function at x is the limit of the difference quotient as h approaches zero. z+h) f(z F'(z) = 1}120 w
