Question

find f(n(x)) when f(x)=x-3 and n(x)=3x-5

Answer 1

to get f(n(x)), just replace x in f(x) by n(x)=3x-5

Answer 2

So, 3(x-3)-5?

Answer 3

nopes, what u did is reverse,
u put x in n(x) by f(x)=x-3
you had to put 'x' in f(x) by 3x-5

Answer 4

So, (3x-5)-3

Answer 5

yes, that is correct f(n(x))

Answer 6

and it can be simplified

Answer 7

3x-8

Answer 8

thats correct final answer :)

Answer 9

can you help me with one more?

Answer 10

sure

Answer 11

k(h(x)) when k(x)=x\[^{2}\]+4 and h(x)=x+2

Answer 12

when K(x)=x^2 +4
and h(x)=x+2

Answer 13

to get k(h(x)), just replace 'x' in k(x) by h(x) = x+2

Answer 14

wherever u see x in k(x) , replace it by x+2

Answer 15

x+2+2, x+4?

Answer 16

nopes,
