Even, Odd or Neither

Front

What is an even function?

Back

A function f(x) is called even if for every x in the domain, f(-x) = f(x). Graphically, even functions are symmetric about the y-axis.

What is an odd function?

Back

A function f(x) is called odd if for every x in the domain, f(-x) = -f(x). Graphically, odd functions are symmetric about the origin.

Front

What does it mean if a function is neither even nor odd?

Back

A function is neither even nor odd if it does not satisfy the conditions for being even or odd. Its graph does not exhibit symmetry about the y-axis or the origin.

Front

Identify if the function f(x) = x^2 is even, odd, or neither.

Back

Even (since f(-x) = (-x)^2 = x^2 = f(x)).

Front

Identify if the function f(x) = x^3 is even, odd, or neither.

Back

Odd (since f(-x) = (-x)^3 = -x^3 = -f(x)).

Front

Identify if the function f(x) = x^4 + x^2 is even, odd, or neither.

Back

Even (since f(-x) = (-x)^4 + (-x)^2 = x^4 + x^2 = f(x)).

Front

Identify if the function f(x) = x^5 + x^3 is even, odd, or neither.

Back

Odd (since f(-x) = (-x)^5 + (-x)^3 = -x^5 - x^3 = -f(x)).
