## anonymous one year ago The table shows the outputs y for different inputs x: Input (x) 3 7 11 15 Output (y) 4 6 8 10 Part A: Do the data in this table represent a function? Justify your answer. (3 points) Part B: Compare the data in the table with the relation f(x) = 5x – 21. Which relation has a greater value when x = 11? (2 points) Part C: Using the relation in Part B, what is the value of x if f(x) = 99? (5 points)

How would you define a function?

2. jdoe0001

well, a function means, no X-REPEATS if the function has any x-repeats in its "input" values, then is NOT a function

so.... any ideas? $$\begin{array}{ccllll} x&y \\\hline\\ 3&4\\ 7&6\\ 11&8\\ 15&10 \end{array}$$
