Question 939669

the function is one-to-one if each {{{x-value}}} has {{{one}}} corresponding {{{y-value}}} and vice versa

use Horizontal Line Test, a test to determine if a function is one-to-one

 If a horizontal line {{{intersects}}} a function's graph {{{more}}} than {{{once}}}, then the function is {{{not}}} one-to-one.

your graph, so far I can see when I zoom in, has a part of line in the middle that goes along x-axis which is horizontal line in this case; so, that means more then one value of {{{x}}} has value of {{{y=0}}}
if so, the function is  {{{not}}} one-to-one
