Answer:

B.14

Explanation:

We are given that

[tex]f(x)=3x^2+1[/tex]

[tex]g(x)=1-x[/tex]

We have to find the value of (f-g)(2)

[tex](f-g)(x)=f(x)-g(x)[/tex]

[tex](f-g)(x)=3x^2+1-(1-x)=3x^2+1-1+x=3x^2+x[/tex]

Substitute x=2

Then, we get

[tex](f-g)(2)=3(2)^2+2[/tex]

[tex](f-g)(2)=12+2=14[/tex]

Hence, the value of (f-g)(2)=14
