Determine whether the function f(x)=4x^3 is even or odd

slega [8]

Answer:

Step-by-step explanation:

Answer:

odd function

Explanation:

To determine if a function f(x) is even/odd consider the following.

• If f(x) = f( -x) , then f(x) is even

Even functions are symmetrical about the y-axis.

• If - f(x) = f(-x) , then f(x) is odd

Odd functions have symmetry about the origin.

Test for even function

f(−x)=4(−x)3=−4x3≠f(x)

Since f(x) ≠ f( -x) , then f(x) is not even

Test for odd function

−f(x)=−(4x3)=−4x3=f(−x)

Since - f(x) = f( -x) , then f(x) is odd

graph{4x^3 [-10, 10, -5, 5]}
