Concept explainers
Choose the true statement which describes the end behavior of the graph.
Answer to Problem 2PFA
Option A is correct.
Explanation of Solution
Given:
Four options are given to match with the end behavior of the graph.
A: As x decreases, the value of y increases; as x increases, the value of y decreases.
B: As x decreases, the value of y decreases; as x increases, the value of y increases.
C:As x decreases, the value of y increases; as x increases, the value of y decreases.
D: As x decreases, the value of y increases; as x increases, the value of y decreases.
Concept Used:
From the graph choose some points from the graph to check the end behavior of the graph and also look at the graph and see the behavior of the end of the graph.
Calculation:
Now choose some points from the graph. 1) from negative side of x – axis: (0,-5), (-1,-9) , (-2,10), From negative side of x – axis, we can see than the end of the graph is going up of y axis, Remark: As x decreases, the value of y increases 2) From positive side of x – axis, we can see than the end of the graph is going down of y axis, Remark: As x increases, the value of y decreases. |
Option A: As x decreases, the value of y increases; as x increases, the value of y decreases.
Remark: Option A is correct for the end behavior of the graph.
Thus, option A is correct.
