Question
1) Recall that we discussed one of the tallest men who ever lived, Robert Wadlow. The equation that approximates the relationship between Wadlow's age and height is h 2.6a+51, where h denotes the height in inches and a denotes age. Why is the relationship between Wadlow's age and height a function? (objective 3 and 4-preliminary ideas) ANSWER: 2) Indicate whether the following are functions. Give a reason for your answer. (objective 3 and 4- preliminary ideas) a) ((6, 4), (-2, 3), (1, 5), (6,-8) ANSWER: b) 3) Evaluate the function,fx)- xt9, at each of the following values of the independent variable, x. x2-81 (objective 3 and 4-preliminary ideas) a) f(-2) ANSWER: b) f(x-3) ANSWER:Explanation / Answer
1. h = 2.6a +51
For every value of a, there is a distinct value of h.So h and a are one to one. Hence the relationship between Wadlow's age and height represents the function.
2. There is a repeated x values that is 6. So its not a function.
