## anonymous one year ago Find f(x) and g(x) so the function can be expressed as y = f(g(x)) y = Seven divided by x squared. + 10

$$f(g(x)) = \dfrac{7}{x^2+10}$$?

@ivorypolnett

4. zzr0ck3r

or $$f(g(x)) = \dfrac{7}{x^2}+10$$

5. anonymous

the second one

6. zzr0ck3r

right I guess that was the point of your period. ok I will give you a hint for one way to do this $$f(g(x)) = f(\color{blue}{\frac{7}{x^2}})=\color{blue}{\frac{7}{x^2}}+10$$

7. zzr0ck3r

what do you think the function $$f$$ needs to be for this to be a true statement?

8. zzr0ck3r

In other words, what function takes something and adds $$10$$ to it?

9. anonymous

I'm honestly not sure.. im sorry

@ivorypolnett I think a part of the question is missing. f(x) should be given before hand

11. anonymous

the problem doesn't give me f(x), im sorry @Harindu

or even g(x)? then there are lots of answers :)
