Answer:

Explanations:
Given the function below:

This equation is an equation of a horizontal line. This means that for a horizontal line, the y-coordinates will be constant for any point on the line while the x-coordinates will take any value.
Using our x-coordinate values to be -1, 1, 2 and 3, the required coordinate pairs for the function g(x) = 4 will be;

Note that any values can be used as the x-coordinates since they all lies on the horizontal line
