Question

Enter the letter of the graph that corresponds to each statement 1. The line is the graph of an increasing function 2. The line is the graph of a constant function 3. The line is the graph of a decreasing function 4. The line is not the graph of a function As with the previous matching problems, you will not be told which of your answers are correct when you submit your answers to this problem. WeBWorK will only tell you if all your answers are correct or not. Some WeBWork problems display a link to additional information or a hint. Follow this link for a hint about graphs in WeBWork.

Explanation / Answer

1. Increasing function : A

(since value of y is increasing with x , slope is positive)

2. Constant function : B

(since for every value of x value of y is same.For each x same y .so it is a function)

3. Decreasing function : C

(since value of y is decreasing with x i.e slope is becoming negative)

4. Not a function : D

( Since, same value of x gives different value of y i.e not a function)
