Answer:

20

Step-by-step explanation:

Given function f(x)=\[x^{2}-x\]

We need to find f(-4) which means we need to find the value of the function when x=-4 .

On substituting x=-4 in the given function:

f(-4)=\[-4^{2}-(-4)\]

Square of -4 is 16.

Hence, f(-4)=\[16+4\]

=20

Hence the value of the given function f(x)=\[x^{2}-x\] when x=-4 is 20.

-3-1=-4
Now, we need to put 2x and -4 together. 

The expression would be 2x-4.
