Any doubt, anywhere, stop me in between and ask me there itself? Okay now?

anonymous · Answer

Of course I will ! thank you so much!

anonymous · Answer

Let us start with our function, see the other openstudy members are studying, and we are attending a function. :)

anonymous · Answer

The function which we are attending is :
$$f(x) = \frac{8}{x^3}$$

anonymous · Answer

Yes.

anonymous · Answer

So, let us draw a table that your question is requiring us to:

anonymous · Answer

Okay, and don't laugh, that is my table. :P

anonymous · Answer

Its beautiful :p

anonymous · Answer

So, you are given with some $x$ values.. Let us take first one:
$x =-4$, right?

anonymous · Answer

Now, you are just plug in the value of $x$ given to you and then find out $f(x)$ corresponding to that $x$ value.

anonymous · Answer

Yes. -4,-3,-2,-1, 0, 1, 2, 3,4

anonymous · Answer

*you are to just plug.......

anonymous · Answer

Like first one I did:
$$f(x) = \frac{8}{x^3} \ f(-4) = \frac{8}{(-4)^3}$$
Getting my this step?

anonymous · Answer

Yes. So far so good.

anonymous · Answer

Now tell me : What is the value of $(-4)^3$ = ?

anonymous · Answer

-64.

anonymous · Answer

Good.

anonymous · Answer

$$f(-4) = \frac{8}{-64} \implies \color{blue}{f(-4) = \frac{-1}{8}}$$

anonymous · Answer

so -1/8 goes in the first box?

anonymous · Answer

Or in decimal form:
$$\color{green}{f(-4) = -0.125}$$

anonymous · Answer

Made sense?

anonymous · Answer

yep, or you can write -0.125 as well. It is your wish.

anonymous · Answer

Will it be okay if i just put -1/8 thought?:)
