Question

If f(x) = 2x - 1 and g(x)=x²-3x-2, find (f+ g)(x).

Answer 1

(f + g)(x) = x² - x - 3

Explanation:

(f + g)(x)

= f(x) + g(x)

= 2x - 1 + x² - 3x - 2 ← collect like terms

= x² - x - 3 ← in standard form

Answer 2

`\text{Given that,}~ f(x) = 2x -1~ \text{and}~ g(x) = x^2- 3x -2 \\\\\text{Now,}\\\\~~~(f+g)(x)\\\\=f(x) + g(x)\\\\=2x-1 +x^2 -3x -2\\\\=x^2 -x -3`
