Linear vs. Non-Linear Functions

Does this graph represent a linear or nonlinear relationship?

• Linear

• Nonlinear

Is this table a function or not a function? Why?

• Function because none of the x-values have more than one y-value.

• Not a Function because the x-value -3 has two different y-values: 1 & 0.

• Not a Function because the x-values aren't in order from least to greatest.

• Function because none of the y-values have more than one x-value.
