f(x) = 2x² + 3x
g(x) = x - 2
We are given these two equations. (f+g)(x) will just be the sum of both f(x) and g(x).
f(x) + g(x) = (f+g)(x)
= 2x² + 3x + x - 2
= 2x² + 4x - 2
Now, just substitute x = 2 into this equation to get (f+g)(2)
2(2)² + 4(2) - 2
= 8 + 8 - 2
= 14
That should be your answer. Let me know if you need any clarifications, thanks!
