A) sure there is one value of y for every value of x
B) in table y = 8
in function
y = 5(11) - 21 = 55-21 = 34
C) 99 = 5 x - 21
5 x = 120
x = 24
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)
