For the function g(x), the graph is shown and the domain of that function is set of all integer numbers.

Domain of a function is all possible input values for that function.

Here, the domain of g(x) is  set of all integers numbers

The x intercept of g(x)

The x intercept is when the value of y is zero, analysing the graph the x intercept can be interpreted as -5 and 1

The y intercept is when the value of x is zero, analysing the graph the y intercept can be interpreted as  1

From the graph,

g(4) is 1

Therefore, For the function g(x), the graph is shown and the domain of that function is set of all integer numbers.
