Question

What is the domain of the graphed function?

A) y ≥ 4
B) x ≥ -2
C) y ≥ -2
D) x ≤ -2

Answer 1

Domain of the function is Option B). x ≥ (-2)

Explanation:

As we know domain of any function is represented by x values of the function and range is represented by the values on y axis

Since the graph continues from x = -2 to the infinity.

Therefore domain of the function graphed is x ≥ (-2).

Answer 2

The domain of a function is the values of x the function can have. Since the function starts from x=-2 and continues in the positive x direction, we can say B) x is greater than or equal to -2 is our domain.
