	\ \
	\ \
	\ \
	\ \
	\ \	\ \

Graph :

1. Draw a coordinate plane.

2. Plot the ordered pairs found in the table.

(b)

Take two points on the graph.

The two points and  should be on the graph of the power function.

The general form of the power function is .

Substitute the point in .

Substitute the point in .

Substitute the value  in .

Substitute in .

Substitute and in general form of power function.

.

Thus, the power function is .
