Graph 20150721 185534

Suppose a point on the curve given above has the property that.

Based solely on the graph above, which of the following is most likely thevalue of the point in question?

Possible Answers:

Correct answer:

Explanation:

如果then the graph must be concave up at the point. Based on the picture, we know that the curve is concave up onat best. The only value that falls on this interval is, which is. Since, this definitely falls on the interval given and we can be sure it is concave up based on the picture.

Example Question #2 :How To Describe Points By Graphing Functions

What is the critical point for?

Possible Answers:

Correct answer:

Explanation:

To find the critical point, you must find the derivative first. To do that, multiply the exponent by the coefficient in front of theand then subtract the exponent by. Therefore, the derivative is:. Then, to find the critical point, set the derivative equal to.
