Which of the following is the best use for the sign chart when graphing rational functions? To determine where the vertical asymptotes are for the graph of F(x) To determine where the maximum is for the graph of F(x) To determine the slope for the graph of F(x) To determine if the graph of F(x) is straight or curved

Solution

Option B is the answer....

When u use a sign chart, we will use it for the derivative of the function... And a positive derivative indicates an increase and a negative derivative indicates a decrease.. So, where the increase changes to a decrease, thats where the maximum point\'s at

So, option B works out best
