we have
we know that
The domain of a function is the set of all possible values of x
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
In this problem
The domain for x is the interval [0,∞)
All real numbers greater than or equal to zero
The range for y is the interval (-∞,0]
All real numbers less than or equal to zero
The graph in the attached figure
therefore
On a coordinate plane, an absolute value curve opens down and to the right in quadrant 4 and starts at (0, 0)
