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
