Question

Given the functions f(x)=3x−2and g(x)=−4x+1. Find (f+g)(x) and simplify completely.

Answer 1

(f+g)(x) = -x - 1

Explanation:

f(x)=3x−2

g(x)=−4x+1

(f+g)(x) = 3x -2 -4x+1

= -x - 1

Answer 2

`\\ \sf\Rrightarrow f(x)=3x-2`

`\\ \sf\Rrightarrow g(x)=-4x+1`

Now

`\\ \sf\Rrightarrow (f+g)(x)`

`\\ \sf\Rrightarrow f(x)+g(x)`

`\\ \sf\Rrightarrow 3x-2+(-4x+1)`

`\\ \sf\Rrightarrow 3x-2-4x+1`

`\\ \sf\Rrightarrow 3x-4x-2+1`

`\\ \sf\Rrightarrow -x-1`
