Algebra-2

It can be seen from the graph that when x < 0, it is a gradually increasing curve, and when x > 0, it is a gradually decreasing curve, with both curves symmetric about the y-axis, let’s analyze the characteristics of this relation:

Analysis of the Relation

1.Is it a Function?

A relation is a function if each input ( x ) has exactly one output ( y ).

Given that for every value of ( x ) (both positive and negative), there is exactly one corresponding ( y )-value, this relation is a function.

2.One-to-One Function?
