Question

Using the following f and g given below, find f•g and g•f. Check whether f•g= g•f
i) f(x) = 3+x, g(x)= x-4​

Answer 1

Answer:

Using the following f and g given below, find f•g and g•f. Check whether f•g= g•f

i) f(x) = 3+x, g(x)= x-4

Answer 2

Answer:

if f(1)=3+1, then g(1)=1-4

f=4, g= -3

then according to commutative property

(4)(-3)=(-3)(4)

LHS=RHS
