Question

Determine the domain ​

Answer 1

Domain [-7, 7]

Explanation:

Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis from -7 to +7

Answer 2

`-7\leq x<7`

Explanation:

the closed circle point indicates that x is equal to -7, while the open circle point indicates x is equal to LESS than seven.
