The video tutorial explains how to determine if a function is even or odd using graphical and algebraic representations. It covers the symmetry of functions about the Y-axis and the origin, and provides methods to test for symmetry. The tutorial also addresses common misconceptions about function exponents and symmetry, using examples to clarify these concepts.

What is a key characteristic of an even function in terms of its graph?

• It has no symmetry.

• It is symmetrical about the origin.

• It is symmetrical about the Y-axis.

• It is symmetrical about the X-axis.

How can you determine if a function is odd using its algebraic expression?

• Check if F(X) equals -F(-X).

• Check if F(-X) equals -F(X).

• Check if F(-X) equals F(X).

• Check if F(X) equals F(-X).

What happens when you plug in -X into an even function?

• You get zero.

• You get a completely different function.

• You get the negative of the original function.

• You get the original function.

What is a common misconception about determining if a function is even?

• Assuming a function is even if it is symmetrical about the X-axis.

• Assuming a function is odd if it is symmetrical about the Y-axis.

• Assuming a function is odd if it has an odd exponent.

• Assuming a function is even if it has an even exponent.

Which of the following is true for a function that is neither even nor odd?

• It is symmetrical about the origin.

• It has no symmetry about the X or Y axes.

• It is symmetrical about the X-axis.

• It is symmetrical about the Y-axis.

If a function is symmetrical about both the X and Y axes, what can be concluded?

• The function is odd.

• The function is both even and odd.

• The function is even.

• The function is neither even nor odd.

What is the result of factoring out -1 from an odd function?

• You get zero.

• You get the original function.

• You get the negative of the original function.

• You get a new function.
