Question

For f(x) = 3x + 1 and g(x) = x2 - 6, find (f + g)(x).

Answer 1

Answer:

x^2+3x-5

Step-by-step explanation:

f(x) = 3x + 1

g(x) = x^2 - 6,

(f + g)(x)= 3x + 1 +x^2 - 6,

Combine like terms

        = x^2+3x-5

Answer 2

Answer:

${x}^{2} + 3x - 5$

Step-by-step explanation:

$f(x) = 3x + 1 \\ g(x) = {x}^{2} - 6 \\ (f + g)(x) = (3x + 1) + ( {x}^{2} - 6) \\ = 3x + 1 + {x}^{2} - 6 \\ = {x}^{2} + 3x - 5$
