Question

Let f(x) = 5x²-2 and let g(x) = 3x + 1. Find (f + g)(2).
(f+g)(2)= (Simplify your answer.)

Answer 1

`\quad \huge \quad \quad \boxed{ \tt \:Answer }`

`\qquad \tt \rightarrow \:(f+g)(x) = 5x² + 3x - 1`

`\large \tt Solution \: :`

`\qquad \tt \rightarrow \: f(x) = 5 {x}^(2) - 2`

and

`\qquad \tt \rightarrow \: g(x) = 3x + 1`

We need to find : (f + g) (x) = ?

`\qquad \tt \rightarrow \: (f + g)(x) = f(x) + g(x)`

`\qquad \tt \rightarrow \: (f + g)(x) = 5 {x}^(2) - 2 + 3x + 1`

`\qquad \tt \rightarrow \: (f + g)(x) = 5 {x}^(2) + 3x - 1`
