Which statement best describes how to determine whether f(x) = 9- 4x4 is an odd function?

vitfil [10]

Answer:

Option C.

Step-by-step explanation:

Note: In the given function the power of x should be 2 instead of 4, otherwise all options are incorrect.

Consider the given function is

$f(x)=9-4x^2$

If $f(-x)=f(x)$ , then $f(x)$ is an even function.

If $f(-x)=-f(x)$ , then $f(x)$ is an odd function.

Now, substitute x=-x in the given function.

$f(-x)=9-4(-x)^2$

$f(-x)=9-4(x)^2$

$f(-x)=f(x)$

So, the given function not an odd function. It means it is an even function.

To check whether the given function is odd, we have to determine whether $9-4(-x)^2$ is equivalent to $-(9-4(x)^2)$ .

Therefore, the correct option is C.

Please solve this question

oee [108]

Answer:

$\frac{1}{81}$

Step-by-step explanation:

Using the rule of exponents

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$

Evaluating from the inside parenthesis outwards

$(-\frac{1}{3}) ^{2}$ = - $\frac{1}{3}$ × - $\frac{1}{3}$ = $\frac{1}{9}$ , then

$(\frac{1}{9}) ^{-2}$ = $\frac{1}{9^{-2} }$ = 9² = 81 , then

$(81)^{-1}$ = $\frac{1}{81}$

The graph of the function, f(x)=-2x^2+6x-3,opens up or down and has a minimum or maximum value.

Volgvan

it opens down because before x^2 is -2 (if it would be 2, it would open up)...and function, which opens up has a maximum value every time
