Looking through my old calc notes, I am reading that f(x) needs to be continuous on [a,b] and f ' (x) also needs to be continuous on [a,b]. Both conditions are needed. If you had to pick just one, then I'd say f(x) being continuous is much more important. Though I'm not 100% sure on this one. My thinking is that if there was any discontinuities on f(x), then the arc length would be distorted and overblown. The arc length should not account for any piece that isn't on the curve.

A factory produces 2354 hammers every hour. Which expression can be used to find how many hammers the factory produces in 3 hour

ki77a [65]

An expression might be: 2354h / 3hrs. You can make the real division sign if you're using paper. Hope this helped :)
