Having a pdf V and then defining a new one as W=V+1 & range of values

#1
The question goes as follows, there's a function V that equals 0.5 for -1<v<=1 and 0 otherwise. From this we define a new function W that is defined as V+1 (also Z=3V+2). What will be W's range of values?

Intuitively I want to go the normal graph transformations route and simply add 1 to both values, but I at the same time feels this is not the right way to go about it?

Any and all help much appreciated! :) Very very lost undergrad checking in.
