a) No or Yes: The following ordered-pairs can represent a mathematical function. (0, 2) (5, 3) (-3, -2) (-7, 8) (0, 5) (10, 0) The next two questions use: z(n) = 5(n)2 + 2(n) + (n)(n-1) b) Evaluate: z(1) c) Evaluate: z(-1) The next two questions use the following: The circumference C of a circle is directly proportional to its diameter d; in other words, C = Pi * d, where Pi approximates 3.14. d) Explain why the circumference of a circle is a function of its diameter. e) A circle with a circumference of 50 inches has a diameter of what? The next four questions use the function: w(t) = -(t) domain for w(t) is: -2 ≤ t ≤ 2, where t is an integer f) List all of the valid inputs for the function w(t). g) Specify the range for the function w(t) h) Evaluate: w(5) i) Evaluate: w(-1) + w(0) + w(1) j) Plot and label the following ordered-pairs on a graph. (1,2) (-2,3) (-3,-5) (0,0) (0,5) (-4,0) (1,-3) k) Briefly explain why the ordered-pairs in the previous exercise cannot represent a function.
