Answer 1-10

Take this test as you would take a test in class. After you are finished, check your work against the answers given in the back of the book. (0. 3.) 1. Identify the vertex and intercepts of the graph of v = x- + 4r - 3. 2. Write an equation of the parabola shown at the right. 3. -0) 3. Find all the real zeros of ((x) = 4c' + Ar + x. Determine the multiplicity of each zero. Figure for 2 4. Sketch the graph of the function /(x) = =r + 7x - 6. 5. Divide using long division: (3x] + 4 - 1) + (x3 + 1). 6. Divide using synthetic division: (2r* - 5x- - 3) = (r - 2). 7. Use synthetic division to evaluate f(-2) for f(x) = 314 - 68 + 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. "(1) = 214 - 313+ 161 - 24 9. /(x) = 3x5 + 24 - 3x - 2 10 Find all the zeros of the function (() = r - 72 + Ilx + 19 and write the polynomial as the product of linear factors
