65. Consider the accompanying graph of f(x) = k ∙ , where n is a positive integer. a. Is n even or odd? b. Is k > 0 or is k < 0? c. Is f(-1) > 0 or is f(-1) < 0? d. Does f(-x) = f(x)? e. As x → +∞, f(x) → ____ f. As x → −∞, f(x) → ____ 66. Consider the following graphs of four functions of the form y = , where n > 0. 16
Which functions: a. Are symmetric across the y-axis? b. Are symmetric about the origin? c. Have an even power n? d. Have an odd power n? e. Have k < 0? 67. From the graph of each quadratic function, identify whether the parabola is concave up or down and hence whether the function has a maximum or minimum. Then estimate the vertex, the axis of symmetry, and any horizontal and vertical intercepts. 68. Find the coordinates of the vertex for each quadratic function listed. Then specify whether each vertex is a maximum or minimum. a. y = 4 b. P(n) =( ) c. f(x) = -8 d. Q(t) = -( ) 69. For each of the following quadratic functions, find the vertex (h, k) and determine if it represents the maximum or minimum of the function. a. f(x) = -2 ( − 3 + 5 c. f(x) = -5 ( + 4 - 7 b. f(x) = 1.6( + 1 + 8 d. f(x) = 8( − 2 – 6 70. Construct an equation for each of the accompanying parabolas. 17
