If f(x) = x³, evaluate the difference quotient . f(2 + h) - f(2) and simplify your answer. h If you have had difficulty with these problems, you should look at Sections 1.1-1.3 of your text.

The rate of change of an autocatalytic chemical reaction is kQxkx2 where Q is the amount of the original substance, x is the amount of substance formed, and k is a constant of proportionality. Factor the expression.

Find f(1) and f(2). f(x)=x+7

Graph the quadratic function f(x)=2x24x3 first using the properties as we did in the last section and then graph it using transformations. Which method do you prefer? Why
