Try dividing f/g (x), what do you get?
I'll tell you the restriction after you find f/g.

anonymous · Answer

i have no idea how to even do that...

Okay, let's see then.

Try solving this?

f(x) = 51
g(x) = 3
$$(\frac{f}{g}) x = \frac{f(x)}{g(x)} = ?$$

anonymous · Answer

where did you even get 51 and 3??

akashdeepdeb · Answer

It is a question I made up. Can you solve it? :)

anonymous · Answer

i really dont need to learn how to do this. Im doing some math homework for a friend to make money to buy my 2 month old some formula ;-;

I am sorry, OpenStudy does not give direct math answers. It is against the OpenStudy honor code. 

All I can tell you is; Solving for a question like that is just like solving for a division question.

In your question:
$$f(x) = 2x + 1$$$$g(x) = x^2 - 7$$
And you have to find: $$(\frac{f}{g}) (x) = \frac{f(x)}{g(x)}$$
You can simply divide them now, and try not to have '0' in the denominator because that gives an undefined value in math.
So,
$$\frac{f(x)}{g(x)} = \frac{2x+1}{x^2-7}$$
But $x^2-7$ (or the denominator) should never equal zero. So find the values when $x^2 - 7 \neq 0$

Getting this? :)

This does not help, i'll go somewhere else.
