For each pair of functions, find $[g \sigma f](x), [f \sigma g](x), and [f \sigma g)(6)$

2. ineedhelp10

a. f(x)=2x-3; g(x)=4x-8 b. f(x)=8=x^2: g(x)=x^2+x+1

@Hero but how would you solve it?

6. Hero

One moment

7. ineedhelp10

yeah its fine

8. Hero

9. ineedhelp10

ah okay so then for the next one you do it the other way around right?

10. ineedhelp10

what about [f*g](6) ? the * is supposed to be the little circle

11. ineedhelp10

but where would you plug in the 6 into the problem then?

12. Hero

Actually, if you have to compute f*g (6) Instead of f(g(6)) then the process for that is different

13. ineedhelp10

so then how will that look like?

14. Hero

15. ineedhelp10

so what?

16. Hero

It means you have to multiply the functions then evaluate @ x=6

I wish you could post the original Instructions directly from your textbook or computer. Based on what you told me, the original problem you posted are not exactly correct as written.
