Here we go ~
First of all, it's a graph of mod function, which is transformed.
So, let's proceed with taking graph of modulus initially ~
The required can be tranformed by moving it three units left and four units down.
so, we need to add 3 to x within the function to move it left by units.
i.e
Now, to move it down by 4 units we need to subtract 4 from the whole function.
So, the correct choice is : C
