Question

What is the domain of the function graphed above?

A. {7/2}
B. -[infinity] < x < [infinity]
C. -2 ≤ x < [infinity]
D. -10 ≤ x ≤ 10

Answer 1

The domain of the function is -2 ≤ x < ∞.

Step-by-step explanation:

The domain of a function represents all the possible input values for the function. In this case, the function is a horizontal line between 0 and 20. Since the graph of the function is a horizontal line, the value of the function will be the same for any input between 0 and 20. Therefore, the domain of the function is -2 ≤ x < ∞, which corresponds to option C.
