(c) Are your estimates in parts (a) and (b) upper and lower estimates? Ex- plain. (A) (b) is a lower estimate and (a) is an upper estimate since v is a decreasing function of t. (B) (a) is a lower estimate and (b) is an upper estimate since v is an increasing function of t. (C) (a) and (b) are neither lower nor upper estimates since v is neither an increasing nor decreasing function of t. (d) Let's find an overestimate and underestimate of the distance traveled by the motorcycle during this time period.
