Unformatted text preview: MAC 1105 Module Test 10 Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Classify the polynomial as cubic or quartic. 1) f(x) = 12x 4- 12 + 0.18x 2- 5x A) Cubic B) Quartic Solve the problem. 2) A population of birds in a small county can be modeled by the polynomial f(x) = x 3- 57x 2 + 1162x + 1094, where x = 1 corresponds to July 1, x = 2 to July 2, and so on. For what days does f estimate the population to be 8550? A) July 12th B) July 11th C) July 14th D) July 13th Classify the polynomial as cubic or quartic. 3) g(x) = 282x 2 + 4147x 3 A) Cubic B) Quartic Determine a window which gives a complete graph of the polynomial function. 4) y = 3x 3- 26x 2 + 18x- 47 A) [- 5, 5] by [- 500, 100] B) [- 8, 10] by [- 100, 300] C) [- 3, 10] by [- 400, 100] D) [- 10, 10] by [- 150, 150] State whether the leading coefFcient is positive or negative....
