Help pls

Try : f(x) = x^3 g(x) = x+5

thts right how did u do tht

8. Nnesha

f(g(x)) means substitute x for g(x) function into f(x) $\huge\rm f(\color{ReD}{g(x)})=(\color{ReD}{x+5})^3$ here is an example find f(g(x) ) when f(x) = x and g(x)= 2x so you should substitute x for 2x into f(x) function $\large\rm f(\color{ReD}{g(x)})=\color{ReD}{x}~~~~~~~~~~~~~~f(\color{Red}{g(x)})=\color{Red}{2x}$

9. Nnesha

make sense ? or do you need more explanation ?

i does not make sense

i don't get wht u tryna say

@ganeshie8

13. Nnesha

well f(g(x)) means f of g of x so we should replace x with the entire equation g(x) |dw:1442155749234:dw|

i still dont get it

15. Nnesha

so same way |dw:1442156175329:dw|

16. Nnesha

i apologize if that didn't help

it is fine thnxs for helping but i dont get it

18. Nnesha
