5 questions are presented in this page and more may be accessed using the applet below.
Question 1: Find the composition function (f _{o} g) (x) and its domain.
f(x) = x + 1 , g(x) = 3x
Question 2: Find the composition function (f _{o} g) (x) and its domain.
f(x) = x^{ 2} + 1 , g(x) = sqrt(2 x)
Question 3: Find the composition function (f _{o} g) (x) and its domain.
f(x) = sqrt(-x + 1) , g(x) = x^{ 2} - 8
Question 4: Find, if possible, (f _{o} g) (-2).
f(x) = 2x + 1 , g(x) = x^{ 2}
Question 5: Find, if possible, (f _{o} g) (0).
f(x) = 1 / (x + 1) , g(x) = 1 / (x - 1)More Question on Composition of Functions - Using an applet
