Answer #1

We are asked the range of values of Q for which revenue function is increasing i.e. for what values of Q will revenue increase when Q increases. A function is increasing when the slope of the function is greater than zero and decreasing when the slope is less than zero. Hence to find out where the revenue function is increasing in Q , we need to find out at what range of Q will the slope of revenue function be greater than zero. Hence the greater than sign.
