Find functions f and g such that h = g ∘ f. (note: the answer is not unique. enter your answers as a comma-separated list of functions. use non-identity functions for f and g.) h(x) = 1 x2 − 81

It is given in the question that

And

can also be written as

Therefore,

That gives,

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
