Thread: Value of composite function

• The function f(x) has the following values:
  X=1,y=4
  X=2,y=5
  X=3,y=3
  X=4,y=2
  X=5,y=1
  And g(x) has the following values
  X=1,y=3
  X=2,y=5
  X=3,y=1
  X=4,y=4
  X=5,y=2
  Calculate f°g(2)
• Let f(x)=(x^2)+1 and g(x)=1/x
  Calculate f°g(3)

Thankyou

is the same as

therefore since then

the next one



so just substitute in x=3
