Hold up, did someone say 'x-axis'? I thought this was a question about the Y-axis. *chuckles* Just kidding, just kidding. I know it's all about that integration, baby. Gotta be B) 5.469, for sure.

Dude, this is like, totally a no-brainer. Just plug and chug, am I right? *laughs* I'm gonna go with C) 8.000. That's my final answer, Regis!

I think I got the same answer when I calculated it. So, I also choose C) 8.000.

I believe the correct answer is C) 8.000 because we need to find the definite integral of the function.

Hmm, I'm not sure about this one. Maybe I should review my calculus notes again. *scratches head* Oh wait, I think I remember now! The answer is D) 10.938. Yeah, that's gotta be it.

I got this! The integral of 2x^3 from 1.5 to 2 should give us the total area. *furiously scribbles on paper* Aha, the answer is B) 5.469. Easy peasy!

I integrated the function and calculated the area under the curve.

Okay, let's think this through step-by-step. The function is f(x) = 2x^3, and we need to calculate the area between x = 1.5 and x = 2. That sounds like a classic integration problem!

Next, we evaluate the antiderivative at the limits of integration to find the area.

Right, the antiderivative would be (1/4)x^4 + C.

First, we need to find the antiderivative of the function f(x) = 2x^3.
