What is the value of the function at x = 2?

Solution:

To make it simple, first construct a vertical line at x = 2

Determine where both the vertical line and the graph intersects

Draw that point of intersection.

Similarly construct a horizontal line which goes through the point of intersection.

This horizontal line explains the value of the function

The value of the function here at x = 2 is -2.

Therefore, the value of the function is -2.

What is the value of the function at x = 2?

Summary:

The value of the function here at x = 2 is -2.
