I'd choose Option B, but only if I had a time machine to go back and double-check my calculus notes. Seriously, who comes up with these Maclaurin questions anyway? Sadists, that's who.

I think I remember the Maclaurin expansion, but it's been a while.

I chose Option B too, but I'm not confident about it.

Hmm, this is tricky. I'm going to go with Option C, just because it's the only one with a square term. Gotta love those second-order expansions, am I right?

Second-order expansions can be tricky, but Option C seems to fit the bill.

I agree, Option C looks like the right choice with that square term.

I'm pretty sure Option A is the right answer. The Maclaurin series for e^x is 1 + x + x^2/2, so for e^(2x) it would be 1 + 2x + 2x^2/2.

That makes sense, Option A it is.

I disagree, I believe it is Option B because of the exponential function.

Option D looks correct to me. The Maclaurin expansion of e^(2x) up to the second order term should be 1 + 2x + 2x^2.
