Question

If f(x) = 2x + 3 and g(x) = 3x - 9, find (f + g)(x).5x - 6X + 66x + 56 - 5xI am not sure if my answer is right please help me

Answer 1

If f(x) = 2x + 3 and g(x) = 3x - 9, find (f + g)(x). We do

`\begin{gathered} f(x)+g(x)=2x+3+3x-9 \\ =(2x+3x)+(3-9) \\ =5x-6 \end{gathered}`

So the answer is: your answer is right
