Question

The graph of part of linear function g is shown on the grid.

Which inequality best represents the domain of the part shown?


−3≤x<7

−3
4≤g(x)<8

4

Answer 1

-3 < x ≤ 7

Explanation:

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

We can see from the graph that our x-values that can be inputted are from -3 to 7. Since -3 is an open dot, we cannot include this in our domain.

∴ -3 < x ≤ 7
