Given that the graph is 

Step-by-step explanation

Step 1.

Consider the graph as follows:

The derivative of a function at a point is found from the graph of the function by fixing a tangent line to the graph at the point given.

A tangent line is a straight line that heads in the same direction as the graph when it is fixed to a specific point.

By this construction, the slope of the tangent line is the same as the slope of the curve at that point and the value of the slope is the derivative of the function at that point.
