Answer:

Domain:  (-∞, ∞); range:  (-∞, ∞).

Step-by-step explanation:

In the given function, f(x)= -2x + |3sinx|, the range of the |3sinx| term is [0, 3].  That of the -2x term is (-∞, ∞).  

The range of f(x)= -2x+|3sinx| is thus  (-∞, ∞); the |3sinx| term has no effect on this.

There are no restrictions on the input to f(x)= -2x+|3sinx|.  The domain is thus (-∞, ∞).
