What is a composite function?

• A function that is subtracted from another function

• A function that is added to another function

• A function that is multiplied by another function

• A function that is combined with another function

If f(x) = 2x + 1 and g(x) = x^2 + 1, what is f(g(x))?

• 2x^2 + 3

• 2x + x^2

• x^2 + 2

Why does the order of composite functions matter?

• Because it affects the final result

• Because it affects the function type

• Because it affects the range

• Because it affects the domain

What is the result of g(f(x)) if f(x) = 2x + 1 and g(x) = x^2 + 1?

• 4x^2 + 4x + 2

• 2x^2 + 3

• x^2 + 2x + 1

• 4x^2 + 3
