You can put this solution on YOUR website!
You can find a value for the function or functions only for a given or known x value. Otherwise, you can only find the function subtraction and the function product, and simplify each.


f-g
2x-4-x%5E2-3
-x%5E2%2B2x-7


f*g
%282x-4%29%28x%5E2%2B3%29
2x%5E3-4x%5E2%2B6x-12----or factorize if you want.
