Answer

Answer:

C. Determine whether $9 - 4(-x)^{2}$ is equivalent to $-(9 - 4x^{2})$.

Explanation:

Step1: Recall odd - function definition

A function $y = f(x)$ is odd if $f(-x)=-f(x)$ for all $x$ in the domain of $f$.

Step2: Find $f(-x)$ for $f(x)=9 - 4x^{2}$

Substitute $-x$ into $f(x)$: $f(-x)=9 - 4(-x)^{2}$.

Step3: Find $-f(x)$ for $f(x)=9 - 4x^{2}$

$-f(x)=-(9 - 4x^{2})$.

Step4: Check odd - function condition

To determine if $f(x)$ is odd, we need to check if $f(-x)=-f(x)$, that is, whether $9 - 4(-x)^{2}$ is equivalent to $-(9 - 4x^{2})$.
