Hi there, in this question, we have to find the rate of change.
00:04
So what is the rate of change? we just call the rate of change as the derivative of any function.
00:11
For example, if you have a function f of x, in order to find the rate of change, rate of change of the function f of x, so you have to just take the derivative of the function, which is the derivative of the function.
00:25
So we can just denote the derivative of the function as f derivative f of x.
00:29
So in this question, again, s of t is given, which is the sales of a math performance in this function.
00:38
So an st is in millions of dollars.
00:41
So in order to find the rate of change for this function, we have to take the derivative of the function...
