Join Nagwa Classes

Attend live General Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to decide whether a function is even, odd, or neither both from a graph of the function and from its rule.

Students will be able to

determine the parity of a function, classifying it as even, odd, or neither,
understand the algebraic conditions that need to be satisfied for a function to be
- even: ,
- odd: ,
understand the graphical condition of symmetry needed for a function to be
- even: reflectional symmetry in the ,
- odd: rotational symmetry of order 2 about the origin.
