What are the domain and the range of this function?
D:
R:
X
OD OD
y

Answer 1

Explanation:

the domain is the interval or set of all valid x values.

the range is the interval or set of all valid y values.

we see in the graphic that x runs from -5 to +1.

and y goes from -4 to +7.

the only additional detail to be considered is the type of end point. if it is a filled dot, the value is included (e.g. "<="), if it is a hollow dot, then the value is excluded (e.g. "<").

so, the domain is

-5 <= x < 1

the range is

-4 <= y < 7
