Question

What is the domain and range as an inequality and if you could explain how you got it that would be great

Answer 1

Range

Set of y values

• (-oo,-2)

As -2 is not included (open dot)

Domain

Set of x values

• (0,oo)

0 is not included (open dot)

Answer 2

As per the graph, the function starts at point (0, -2) point it self not included.

The graph is extended down and right, so the given point is maximum of the function.

The domain:

• x > 0 or x = (0, +∞)

The range:

• y < -2 or (- ∞, -2)
