Chapter 3: Q. 340 (page 343)

Determine whether each graph is the graph of a function

Short Answer

Expert verified

First graph and second graph are not graph of a function because vertical line passes through more than one point on graph

Step by step solution

01

Given Information 

Two graphs are given :

02

Part(a) Step 1:  vertical line test

Draw vertical lines on the graph . When vertical lines crosses more than one point on graph then it is not a function .

First graph does not pass vertical line test, so it is not a function .

03

Part(b) Step 1: Vertical line test

Draw vertical lines on the graph . When vertical lines crosses more than one point on graph then it is not a function .

Second graph does not pass vertical line test, so it is not a function

04

Final answer 

First graph and second graph are not graph of a function because vertical line passes through more than one point on graph
