Question

1. domain: (, ) range: (, )

Explanation:

Step1: Define domain

The domain is the set of all possible x - values. Looking at the grid, the left - most x - value is the smallest value in the domain and the right - most x - value is the largest. Assuming each grid square is 1 unit, if we count from left to right, the x - values range from - 5 to 5. So the domain is $[-5,5]$.

Step2: Define range

The range is the set of all possible y - values. Looking at the grid from bottom to top, assuming each grid square is 1 unit, the y - values range from - 5 to 5. So the range is $[-5,5]$.

Answer:

Domain: $[-5,5]$, Range: $[-5,5]$
