nnesha · Answer

danjs · Answer

Put all your x values in the Domain bubble, and Y values in the range bubble. The function draws the lines from the domain to the range. 
You will see that 3 in the domain has 2 lines, one going to 8 and one to -6

danjs · Answer

Each one in the domain, should have only one line going to one value in the range
