3. Part I. Draw a graph of a relation that is not a function (3 points)
1 answer:
The equation of a relation that is not a function is
Relations may or may not be a function.
A relation that is a function will pass the vertical line test, when represented on a graph
An example of a relation that is not a function is
See attachment for the graph of the above relation
The relation is not a function, because it fails the vertical line test

Step-by-step explanation:
Given
x² - 9x + 20 = 0
x² - ( 4 + 5) x + 20 = 0
x² - 4x - 5x + 20 = 0
x ( x - 4 ) - 5 (x - 4 ) = 0
(x - 4 ) ( x - 5 ) = 0
Either
x - 4 =0
x = 4
or
x - 5 =0
x = 5
x = 4 and 5
