Answer:
3x^2-x-6
Step-by-step explanation:
f-g means you are going to do (3x^2-4)-(x+2)
3x^2-4-x-2
Combine like terms
3x^2-x-6
Answer:
[tex](f-g) (x) = 3x ^ 2- x - 6[/tex]
Step-by-step explanation:
We have the following functions
[tex]f (x) = 3x ^ 2-4[/tex]
[tex]g (x) = x + 2[/tex]
To find [tex](f-g) (x)[/tex] we must subtract the function f(x) with the function g (x)
Then we perform the following operation
[tex](f-g) (x) = 3x ^ 2-4- (x + 2)[/tex]
[tex](f-g) (x) = 3x ^ 2-4- x - 2[/tex]
[tex](f-g) (x) = 3x ^ 2- x - 2-4[/tex]
Finally we have that:
[tex](f-g) (x) = 3x ^ 2- x - 6[/tex]
