Answer:

[tex](f\cdot g)(x)=2x^2+10x+12[/tex]

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

[tex](f+g)(1)=10[/tex]

Step-by-step explanation:

[tex]\tt f(x)=x+3[/tex]

[tex]\tt g(x)=2x+4[/tex]

[tex](f\cdot g)(x)=f(x)\cdot g(x)=(x+3)(2x+4)=2x^2+4x+6x+12[/tex]

[tex]=2x^2+10x+12[/tex]

[tex](f-g)(x)=f(x)-g(x)=x+3-(2x+4)=x+3-2x-4[/tex]

[tex]=-x-1[/tex]

[tex](f+g)(1)=f(1)+g(1)=1+3+2(1)+4[/tex]

[tex]=4+2+4=10[/tex]
