#1,
The domain is all of the x-values.
The x-values of the set are: 2, 15, 21, 24
Your answer is C.
#2,
Part A)
Yes, the data in the table represents a function because each x-value has exactly one y-value. Also, the function passes the vertical line test.
Part B)
f(x) = 5x - 21
f(11) = 5(11) - 21
f(11) = 55 - 21
f(11) = 34
The table has a y-value of 8, when x = 11.
Therefore, f(x) = 5x - 21 has a greater value than the table when x = 11
Part C)
f(x) = 99
f(x) = 5x - 21
5x - 21 = 99
5x = 120
x = 24
The value of x is 24.
