SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. If the following is a polynomial function, then state its degree and leading coefficient. If it is not, then state this fact. 1) f(x) = -10x5 + 3x4 +4x3 + 12 Write an equation for the linear function f satisfying the given conditions. 2) f(3) - 5 and f(6) - 6 Write the quadratic function in vertex form. 3) y = x2 - 12x + 40 Solve the problem. 4) Dan's long-distance phone carrier charges him $7.95 a month for service. In addition, Dan is charged 9 cents a minute for the calls he makes. If his monthly bill is $23.34. how many minutes of calls did he make? 5) The length of a rectangle is 5 inches more than the width. The perimeter of the rectangle is 38 inches. Find the width of the rectangle. 6) A projectile is thrown upward so that its distance above the ground after t seconds is h - -16t2 + 448t. After how many seconds does it reach its maximum height? Determine if the function is a power function. If it is, then state the power and constant of variation. 7) f(x) = =x5 Write the statement as a power function equation. Use k as the constant of variation. 8) John kept track of the time it took him to drive to college from his home and the speed at which he drove. He found that the time t varies inversely as the speed r. Graph the function in a viewing window that shows all of its extrema and x-intercepts. 9) f(x) - 3x(x - 1)(x + 2) Find the zeros of the function. 10) ((x) - x3 - 49x Graph the function in a viewing window that shows all of its extrema and x-intercepts. 11) (x) = (x+1)2(x - 1)x - 2) Find the zeros of the polynomial function and state the multiplicity of each. 12) f(x) = -5x2(x - 7)(x + 1)3 Find the zeros of the function. 13) f(x) - 2x3 + 6x2- 8x
