Answer questions 7 and i need and show work and explain

Hey!

Hope this helps...

Question 7:  Is the Graph a 1-to-1?

The answer is: No

Reason: If you look at the graph, you see that when the x value is -1 the y value is -2, when x is 0, y is 0.  When x is 1, y is 2, when x is 3, y is 4, and so on and so on...

Question 9: What is f(2)?

The answer is: When f (or x) is 2, y is 3... so f(2) = 3

Reason: (Look at reason for Question 7)
