PreCalculus CP - Marking Period 1 Quarterly Exam Review KEY Review for Math Analysis CP Q1 1. Determine whether the given function is odd, even or neither. f(x)= x4 + x2 +1 2. Find the average rate of change of f(x) = -2x2 + x from x1 = 2 to x2 = 5. 3𝑥+6 3. Find the inverse of the following function: 𝑓(𝑥) = 4 4. Divide the following and leave your answer in standard form. 5𝑖 3+𝑖 5. Find the zeros of the given function and graph. f(x) = x3+ 4x2 - x – 4 𝑥 6. Find the domain of 𝑓(𝑥) = and put your answer in interval notation. √𝑥+3 7. List all possible rational zeros for f(x) = -3x2 -4x2 +11x + 10 8. Write the equation of a line in slope-intercept form for the line passing through (6, -3) and perpendicular to the line whose equation is : 1 𝑦 =− 𝑥−2 3 9. Find the domain of the composite function f(g(x)), where 3 f(x) = and g(x) = x + 2 𝑥−1 10. Divide the following: (6x3 – x2 – 5x + 4) ÷ (3x-2) 𝑓(𝑥+ℎ)−𝑓(𝑥) 11. Find and simplify the difference quotient for the function ℎ f(x) = 3x2. 12. Write an equation of the line in point-slope form that passes through the −1 point (-6, 3) and parallel to the line whose equation is 𝑦 = 𝑥 + 7. 2 13. Given the function below, evaluate f(-10) 𝑥 + 5 𝑖𝑓 𝑥 ≥ −5 f(x)={ } −(𝑥 + 5) 𝑖𝑓 𝑥 < −5 14. The daily profit in dollars of a new flower shop is described by the function P(x) = -5x2 + 180x -2691, where x is the number of arrangements made in one day. How many arrangements should be prepared in order to maximize profit?
