Someone please verify if I'm correct
For f(x)=4x+1 and g(x)=x^2-5, find (f-g)(x)
A.) 4x^2-19
B.) X^2-4X-6
C.)-X^2+4X-4
D.)6+4X-X^2

The correct answer is C right?
From what I know it should just be (4x+1)-(x^2-5)
Do I need to distribute the minus sign to (x^2-5)?

D is the correct answer
don't be sad because there is -5 and - is also lying there so equation becomes
4x +1 -( x^2 -5)
4x+1 -x^2 +5
6 +4x -X^2 is the correct answer
