Question

using f(x)=x-3 and g(x)=2x-8, evaluate f(g(3))

Answer 1

to find f(g(x)) replace x by g(x)in f(x)
so here
replace x in x-3 by (2x-8)
and tell me what u get...

Answer 2

f(x)=2x-11

Answer 3

right,now to find f(g(3)),put x=3 in that and tell me what u get....

Answer 4

6-11=-5

Answer 5

yup :) u got it..

Answer 6

thank you :)
