Question

Given f(x)=2x^2-8x+6 and g(x)=3x-1 find f(x) +g(x)

Answer 1

For this case we have the following functions:

$f (x) = 2x ^ 2-8x + 6\\g (x) = 3x-1$

We must find f (x) + g (x):

We have to:

$f (x) + g (x) = 2x ^ 2-8x + 6 + (3x-1)\\f (x) + g (x) = 2x ^ 2-8x + 6 + 3x-1$

We add similar terms:

$f (x) + g (x) = 2x ^ 2-5x + 5$

Answer:

$f (x) + g (x) = 2x ^ 2-5x + 5$
