Which of the following would not be a possible function for f (x) and g(x) such that f of g of x is equal to 6 over the quantity x squared end quantity plus 3 f of x is equal to 4 over x plus 2 and g(x) = x2
f of x is equal to 4 over x plus 2 and g of x is equal to 1 over the quantity x squared end quantity
f of x is equal to 4 over the quantity x squared end quantity plus 2 and g(x) = x
f of x is equal to 2 over x plus 2 and g of x is equal to x squared over 2
