I have this problem:
f(x) = 2X^2 + 6x - 1
find f(1/2)
The book says the answer is 5/2.
I can't seem to get this. I am missing something.
f(1/2) = 2(1/2)^2 + 6(1/2) - 1
2(1/4) + 6/2 - 1
2/4 + 6/2 - 1
This is where I am screwing up. I don't know the proper way to proceed.
EDIT I think I got it, does this look legit?
1/2 + 6/2 - 2/2
7/2 - 2/2
5/2
