Which statement best describes how to determine whether f(x) = 9 – 4x2 is an odd function?

A. Determine whether 9 – 4(–x)2 is equivalent to 9 – 4x2.
B. Determine whether 9 – 4(–x2) is equivalent to 9 + 4x2.
C. Determine whether 9 – 4(–x)2 is equivalent to –(9 – 4x2).
D. Determine whether 9 – 4(–x2) is equivalent to –(9 + 4x2).

Option C - determine whether is equivalent to or not.

Step-by-step explanation:

To find : Which statement best describes how to determine whether is an odd function?

Solution :

We have a property for odd functions,

Let f(x) be an odd function then it must satisfy

Now, we have been given the function

For this function to be odd, it must satisfy the above property.

Replace x with -x,

and

Hence, in order to the given function to be an odd function, we must determine whether is equivalent to or not.

Therefore, C is the correct option.

e) none of the above because the measure of angle cba is 101°
