You are adding together functions f(x) and g(x) as follows:

f(x) + g(x) = 3x + 7 + 5x - 2.  Combining like terms, 3x+5x=8x, and -2+5=3.

Thus, (f+g)(x) = 8x + 5.  What is your conclusion?

Answer:  The given statement is TRUE.

Step-by-step explanation:  We are given the following two functions :

[tex]f(x)=3x+7,~~~\textup{and}~~~g(x)=5x-2.[/tex]

We are to check whether the following statement is true or false :

[tex](f+g)(x)=8x+5.[/tex]

We know that for any two functions p(x) and q(x), we have

[tex](p+q)(x)=p(x)+q(x).[/tex]

Therefore, we get

[tex](f+g)(x)\\\\=f(x)+g(x)\\\\=(3x+7)+(5x-2)\\\\=3x+7+5x-2\\\\=8x+5.[/tex]

Thus, [tex](f+g)(x)=8x+5.[/tex]

The given statement is TRUE.
