Question

The graph of an absolute value function opens down and has a vertex of (0, -3). The domain of the function is . The range of the function is .

Answer 1

Domain: (-∞, ∞)

Range: (-∞, -3]

Explanation:

If the graph opens down then the range is based on the vertex and the direction the opening is.

Answer 2

Domain: All real numbers

Range:
`y\leq -3`

Explanation:

The domain is the set of all x values. The quadratic equation continue to operate over all x-values in both directions. The domain is all real numbers.

The range is the set of all y-values. Here the quadratic begins at -3 and continues in a downward direction forever. Then range is
`y\leq -3`
