WebIf f ′ ( b) is positive, the function is increasing on that entire interval . This is because f ′ ( x) is positive at x = b, and can't change sign anywhere else in the interval (similarly if f ′ ( b) is negative). Remember: f ′ ( x) can only change sign at critical points! WebThis is a linear function because for every 1 minute, the clock ticks the same number of times. If we express this situation on a graph, we would observe a straight diagonal ray, starting at (0,0) and increasing towards the upper right. As x (minutes) increases by 1, y (number of ticks) would increase by 60.
