Answer:
9x - 2
Step-by-step explanation:
f(x) = 4x - 8
g(x) = 5x + 6
because it's (f + g)(x), we can simply add the functions together
{note: don't get thrown off by the (x) being separate parentheses--distributing the x first can help it look familiar:
(x)(f + g)
fx + gx,
it's the same thing}
(4x - 8) + (5x + 6)
here, we want to combine like terms to simplify:
4x + 5x - 8 + 6
4x + 5x - 2
9x - 2
So, (f + g)(x) = 9x - 2
hope this helps!! have a lovely day :)
