Take this test as you would take a test in class. After you are finished, check your 5 work against the answers given in the back of the book. (0. 3) -6 1. Identify the vertex and intercepts of the graph of y = x? + 4x + 3. 2. Write an equation of the parabola shown at the right. (3, -6) 3. Find all the real zeros of f(x) = 4x3 + 4x2 + x. Determine the multiplicity of each zero. Figure for 2 4. Sketch the graph of the function f(x) = -x3 + 7x + 6.' 5. Divide using long division: (3x3 + 4x - 1) + (x2 + 1). 6. Divide using synthetic division: (2x4 - 5x2 - 3) + (x - 2). 7. Use synthetic division to evaluate f(-2) for f(x) = 3x4 - 6x2 + 5x - 1. In Exercises 8 and 9, list all the possible rational zeros of the function. Use a graph- ing utility to graph the function and find all the rational zeros. 8. 8(1) = 214 - 313 + 161 - 24 9. h(x) = 3x5 + 2x4 - 3x - 2x 10 Find all the zeros of the function S(x) = x3 - 7x2 + 1 1.x + 19 and write the polynomial as the product of linear factors. In Exercises 11-14, perform the operations and write the result in standard form. 11. (-8 - 37) + (-1 - 15/) 12. (10 + +20) - (4 - -14) 13. (2 + 1)(6 - i) 14.
