Answer:
[tex](f-g)(x)=3^x-4x+12[/tex]
Step-by-step explanation:
The notation "(f-g)(x)" means we subtract the function g(x) from f(x) and get the expression. Very simple.
Let's do this:
[tex]f(x) =3^x+10[/tex]
and
[tex]g(x) =4x -2[/tex]
Now,
[tex](f-g)(x)=[3^x+10]-[4x-2]\\(f-g)(x)=3^x +10 -4x + 2\\(f-g)(x)=3^x-4x+12[/tex]
THis is the expression for (f-g)(x).
