G (x) = x - 4 Can you evaluate (g°f) (0) ? Explain your why or why not.

Model answer:

To evaluate the composition, you need to find the value of function f first. But, f (0) is 1 over 0, and division by 0 is undefined. Therefore, you cannot find the value of the composition.

    Step-by-step explanation:

    For finding out g*f (x) we must have both the functions well defined. Otherwise there is no way to find the composition function value.

    Since we are to find (g°f) (0

    we must have atleast the value of f (0)

    Hence option b is correct

    You technically can't model (gºf) (0) if a f (x) equation is not given to you. Since you only have a g (x) equation, you cannot find (gºf) (0)
