Question

Express the following function, F(x) as a composition of two functions f and g.

Answer 1

F(x)=x^2 over (x^2 +4)

Answer 2

@midhun.madhu1987 can you please help again :)

Answer 3

g(x) = x^2
f(x) = x/(x+4)

then
f(g(x)) = x^2 / (x^2 + 4)

Answer 4

Im sorry @perl i still dont understand

Answer 5

how do express it as a composition of two functions?

Answer 6

you can write
f o g

Answer 7

fog=x^2 over (x^2 +4) ?

Answer 8

or something else?

Answer 9

@ganeshie8 could you please help? :)

Answer 10

@iGreen

Answer 11

sorry, i was helping other people

Answer 12

what was the question?

Answer 13

i dont understand where you were going with the fog part. the question is express the following function F(x) as a composition of two functions f and g @perl

Answer 14

F(x)=x^2 over (x^2 +4)

Answer 15

we are breaking down F(x) into two functions, into a composition of two functions

Answer 16

yea :)

Answer 17

F(x) = f ( g ( x) ) , (caps matters here)

Answer 18

ok

Answer 19

so now, the 'inner' function, i chose to be x^2

Answer 20

g(x) = x^2

Answer 21

we can think of composition as two machines connected to each other

Answer 22

alright, so g(x)=x squared

Answer 23

for the first part
