Answer:
x^2+7x if you are asked to find the difference of a function f and function g
Step-by-step explanation:
We are asked to A-B or f(x)-g(x).
(4x^2+6x)-(3x^2-x)
4x^2+6x-3x^2+x
The like terms I'm going to pair up.
4x^2-3x^2+6x+x
1x^2 +7x
x^2 +7x
The answer is x^2+7x
Answer:
OPTION D: 
Step-by-step explanation:
You know that the area of Rectangle A is given by :

And the area of Rectangle B is given by:

Therefore, in otder to find the function that represents the difference, you need to subtract the functions f(x) and g(x).
Then, you get this function h(x):
