The functionf(x) =x+ex-1is one-to-one. By inspection, what isf-1(0)? what isf-1(e)?3. A tank continuously drains so that the volumeVof water (in gallons) remaining in the tankaftertminutes isV(t) = 100(1-t20)2.(a) What is the domain ofV(t)by the context of the problem? What is the range?(b) What is implied about the physical nature of the problem that ensuresV(t)is one-to-oneon its domain? Find the inverse function.(c) What isV-1(25)? Interpret its meaning in the given scenario.
