Answer:
Third option: 
Fourth option: 
Sixth option: 
Step-by-step explanation:
By definition, we can factor the Difference between two squares:

In order to find which products results in a difference of squares, we need to check each option:

The product does not result in a difference of squares.

Since the signs are equal (
), the product will not result in a difference of squares.
Using Distributive Property for the other options, we get:

The product results in a difference of squares.

The product results in a difference of squares.

Since the signs are equal (
), the product will not result in a difference of squares.

The product results in a difference of squares.
You mean y = b^x.
By plugging different values of x, we find different y-values forming points in the form (x, y).
After 2 or 3 points, we can clearly see that the graph of y = b^x passes through the point (0, 1) and extends forever in the upward direction through quadrant 1.
