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
