whether the relation represented by following graph is a function using vertical line test.
Answer to Problem 13PPE
Given relation is not a function
Explanation of Solution
Given relation:
Solution:
To use the vertical line test , we draw a line parallel to the y- axis for any value of x. If the vertical line intersect the graph more than once for any value of x then the graph in not the graph of a function.
By drawing a line parallel to the y- axis at any point say x= 1, we get
Since this vertical line meet the graph at two points, therefore, given relation is not a function.
