Question

The step function g(x) is defined as shown.

What is the range of g(x)?

–3 ≤ g(x) ≤ 5

0 ≤ g(x) ≤ 10

{–3, 2, 5}

{0, 4, 10}

Answer 1

{-3,2,5}

Explanation:

The range is defined as the values of the dependent axis where the functions is defined, if we plot the function below we can observe that the Y-axis is only defined in three points, -3, 2 and 5. So, the range is the set of integer compounded by those three values.

Rg={-3,2,5}
