Question

(f - g)(x) this is algebra 2 please help me solve this

Answer 1

The formula for the operation (f-g)(x) is,

`(f-g)(x)=f(x)-g(x)`

Determine the expression for (f-g)(x).

`\begin{gathered} (f-g)(x)=f(x)-g(x) \\ =6x+9-x^2 \end{gathered}`

The domain of function is possible values of x for which function is defined.

The function 6x + 9 - x^2 is defined for every value of x. So domain of (f - g)(x) is all real number,
