In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
f(x) = x² for x < 0
5 for 0 ≤ x < 2
x/2 for x ≥ 2
Step 02:
functions:
we must analyze the graph to find the solution.
graph:
The domain is reflected on the x-axis and the range is reflected on the y-axis
domain:
(-oo, 0) U [0 , 2) U [2 , oo)
intercept(s):
(0 , 5)
range:
(0, oo)
That is the full solution.
