Question

What is the range of the function on the graph?

O. all the real numbers
O. all the real numbers greater than or equal to 0
O. all the real numbers greater than or equal to 2
O. all the real numbers greater than or equal to -3

Answer 1

Last Option

All the real numbers greater than or equal to -3

Explanation:

Range is the set of y-values that can be inputted into function f(x).

We see that our y-values range from -3 to infinity. Since -3 is closed dot, we include it in our range:

[-3, ∞) or y ≥ -3
