Respuesta :

(f - g)(x) = f(x) - g(x) = (2x + 1) - (x^2 - 7) = -x2 + 2x + 8 = (x + 2)(4 - x)

Answer:

[tex]f(x)-g(x)=-x^2+2x+8[/tex]

Step-by-step explanation:

We have to find the next expression: [tex](f-g)(x)=f(x)-g(x)[/tex] as we know the [tex]f(x)[/tex] and [tex]g(x)[/tex] then:

[tex]f(x)-g(x)=2x+1-(x^2-7)=2x+1-x^2+7=-x^2+2x+8[/tex]
