Question

Here is a table of values for y = f(x).

X: -5, -3, 0, 2, 6, 7, 9, 10, 13

f(x): 1, 2, 3, 0, 1, 2, 3, 0, 1

Mark the statements that are true.

A. f(-3) = 2
B. f(0) = 10
C. The domain for f(x) is the set (-5, -3, 0, 2, 6, 7, 9, 10, 13).
D. The range for f(x) is all real numbers.

Answer 1

A. f(-3) = 2 is true, based on the table.

B. f(0) = 10 is false, since f(0) = 3 based on the table.

C. The domain for f(x) is the set (-5, -3, 0, 2, 6, 7, 9, 10, 13) is true, since these are all the values of x for which f(x) is defined.

D. The range for f(x) is all real numbers is false, since the values of f(x) are only 0, 1, 2, and 3.
