Is this a function or not? Explain.
Yes - every x is paired with only one y
What is the domain & range of this relation?
Domain: {-4, 1, 5, 6} , Range: {0, 1, 2}
Is this a function or not? Explain
No, it fails the VLT at x=0.

x = 3
Determine if the function is linear or nonlinear. Justify your answer.
Nonlinear: it is not a straight line.
Determine if the relation is linear or nonlinear. Justify your answer.
Linear: x increases at a constant rate (+3) and y increases at a constant rate (-4).
Determine if the relation is linear or nonlinear. Justify your answer.
Linear: x increases at a constant rate (+5) and y increases at a constant rate (+3).
