Question

help with calculus!!!

Answer 1

Find two functions f(x) and g(x) such that f[g(x)] = x but g[f(x)] does not equal x.

Answer 2

@ganeshie8 PLEASE

Answer 3

that's nto very hard

Answer 4

omg please help me :(

Answer 5

try f(x)=x^2 and g(x)=x+1

Answer 6

let's compute the composite functions

Answer 7

f(g(x))=(x+1)^2=x^2+2x+1
g(f(x))=(x^2)+1=x^2+1
are the two equal?

Answer 8

nope

Answer 9

so did we satisfy the conditions of your problem?

Answer 10

oh wow.. that was really easy haahah

Answer 11

there we go then :)
feel free to change the functions a bit. the results will still be different, but you'll have an example that's separate from mine

Answer 12

okay! thanks (:
