You should review problems from practice exams, problem sets, projects, and lecture as well. 1. Evaluate the following limits: lim x 2 x 2 + 6 x - 4 x - 2 lim x 3 - x 2 + 3 x - 18 x 2 - 9 lim x →- 3 + x 2 + 3 x - 18 x 2 - 9 lim x →-∞ 4 x - 3 x 3 x 2 - 1 lim x 2 1 2 - 1 x 2 - 2 2 - x lim x 2 + x 2 + 8 x - 20 | 2 - x | 2. Find an equation of a line L that passes though (-2,2) and is perpendicular to the line repre- sented by the equation 2 y - 8 x = 5 . 3. Find the intercepts of the line L from problem 2. Suppose y represents the number of units of a product (in thousands) that will sell at price x dollars. Interpret the slope and x - intercept of the line in terms of dollars and units sold. 4. Factor the negative exponents and then find all intercepts of the graph of the function: f ( x ) = x (3 x + 4) - 1 2 - (3 x + 4) 1 2 5. Solve the inequality: 8 - 4 x 2 x 6 6. Find the domain of each of the following functions:
