Answer:
Option A
Domain = Range = (-∞,∞)
Explanation:
We can easily solve this question by using a graphing calculator or any plotting tool.
The function is
f(x) = -2x + | 3 sin(x) |
Which can be seen in the picture below
We can notice that f(x) is a line with periodical ups and downs thanks to the sinusoidal term, but there are no restrictions over the domaoin or range of the function.
It can take any real value as an input, and can produce any real value as an output
