Answer:
Domain: all real numbers
Range: all real numbers
Explanation:
The domain is all x values, and the range is all y values.
Domain:
The domain is all real numbers except where the slope is undefined (a vertical line). In this case, no number makes the expression undefined, so the domain is:
all real numbers
Interval notation: (-∞,∞)
all negative numbers and positive numbers (all real numbers)
Set-Builder Notation: x ∈ R
Range:
The range is the set of all valid values. Graph the line and check. Since all values of y are valid, the range is:
all real numbers
Interval notation: (-∞,∞)
all negative numbers and positive numbers (all real numbers)
Set-Builder Notation: x
