Apply rates of change to displacement, velocity, and acceleration of an object moving along a straight line. Predict the future population from the present value and the population growth rate. Use derivatives to calculate marginal cost and revenue in a business situation.
We want to find the increase in total cost when increasing production from 5000 items to 5001 items. This is equivalent to finding the average rate of change on the interval \([5000, 5001]\). The total cost at 5000 items is: \(TC(5000) = 2000 + 50\sqrt {5000} \approx 5535.53\)
Rate of change is established as the ratio between modifications among two quantities. Change is observed when a specific quantity either increases or decreases in value. The mechanism to figure the rate of change adopts the formula; Rate of change = (yf - yi) / (xf - xi)
22 kwi 2021 · Find the average rate of change of a function. Use a graph to determine where a function is increasing, decreasing, or constant. Use a graph to locate local maxima and local minima. Use a graph to locate the absolute maximum and absolute minimum. Gasoline costs have experienced some wild fluctuations over the last several decades.

Find the average rate of change of the \(x\)-coordinate of the car with respect to time. Using the formula, we get \[ \text{Rate} = \dfrac{\Delta x}{\Delta t} = \dfrac{14 - 2}{6 - 0} = 2 \text{ m/s}.\ _\square\]
