What is the domain and range of the graph?

• D: { x | 0 < x < 3}

  R: { y | 0 < y < 36}

• D: { y | 0 < y < 3}

  R: { x | 0 < x < 36}

• D: { x | 0 < x < 36}

  R: { y | 0 < y < 3}

• D: { y | 0 < y < 36}

  R: { x | 0 < x < 3}

Explain the concept of domain and range in function notation.

• The domain is the set of all even numbers, and the range is the set of all odd numbers.

• The domain is the set of all real numbers, and the range is the set of all imaginary numbers.

• The domain is the set of all possible input values, and the range is the set of all possible output values.

• The domain is the set of all positive numbers, and the range is the set of all negative numbers.
