12-19.

Examine the graphs of each relation below. Decide if each is a function. Then describe the domain and range of each. Homework Help ✎

Is there more than one output value for a single input value? If so, it is not a function.

Determine the possible *x*-values to find the domain and the possible *y*-values to find the range.

It is not a function.

R: − 3 ≤ *x* ≤ 3
