Answer:
-2x+1
Step-by-step explanation:
Given the difference of Functions
-(x + 3) - (x - 4),
To combine both functions, first we need to use the mathematical signs to open the brackets. This will give us;
-x-3-x+4
Note that -×- = +
and also -×+ = -
Step 2:
Collecting the like terms
-x+3-x+4
=(-x-x)-3+4
= -2x+1
The combined term results to -2x+1
