I thought it would be more complicated than that!

So, f(3) should be around 10?

f(2) = 8 and f(5) = 14, got it!

I believe the formula is f(x) = f(a) + (f(b) - f(a)) * ((x - a) / (b - a)). I just need to plug in the values correctly!

I’m a bit confused about whether we should use the exact values or if we need to adjust them somehow. I hope I remember the right steps!

I think we just need to find the slope between the two points and then use that to estimate f(3). It feels similar to a question we did last week.

I remember we practiced linear interpolation in class, but I'm not entirely sure how to set up the formula for this one.

Wait, what? Linear what? I'm totally lost on this one. I don't remember learning anything about this in my courses. I'm going to have to guess on this, because I have no idea how to approach it.

Linear interpolation, got it. I remember learning this in my math class. Let me see, I need to use the formula (y2 - y1) / (x2 - x1) to find the slope, and then plug that into the equation y = mx + b to estimate f(3). I think I can do this!

Hmm, I'm a bit unsure about this one. I know linear interpolation is about finding a value between two known points, but I'm not totally confident in the steps to actually calculate it. I'll have to think this through carefully.

Okay, this looks like a straightforward linear interpolation problem. I just need to find the equation of the line between the two given points and then plug in x=3 to get the estimated value of f(3).

I think option C is the way to go. Creating a picklist for the specific search engine and using conditional visibility to show it only when the lead source is "Search Engine" seems like the most straightforward and efficient solution. It keeps the process simple for the user while still meeting the requirement.

Okay, I got this. The formula is defects / total units * 100 to get the percentage of DPU.

I'm worried about this one. The wording doesn't give me enough context to be totally confident. I'll mark this for review later and not spend too much time overthinking it.

Hmm, the LIBOR term structure and the details about the swap and the options quotes are a lot to take in. I'll need to review those exhibits closely to understand the situation.

I bet the answer is 11. Why? Because 11 is the middle number between 8 and 14, duh!

I agree. We can find the equation of the line passing through (2, 8) and (5, 14) to find f(3).
