See explanation below
Explanation:
We use the example of an absolute value to answer
For example: f(x) = |x|
Plotting the function:
when we plot the graph, the features:
It has a V-shape
The graph of an absolute function lies above the x axis
Also, we see the lines spanning towards the negative and positive y axis are of the same size. Hence, the graph is symetric along the y axis
The domain (x values or the input) is all real numbers
[tex]\text{Domain =(-}\infty,\text{ }\infty)[/tex]
The range (y values or the output) is all real numbers greater than or equal to zero.
This is because, the y value starts from 0 then extends upward without ending.
real numbers ≥ 0
[tex]\text{Range = \lbrack{}0,}\infty)[/tex]
