You eliminate or ‘take away’ the answers that you know or think that r wrong. The last answer that’s left is your answer.
Rational number integers because the sum using (LCD) is 13 and 17/24. Therefore, the answer can not be a whole number because it is in a fractional form. You can also put this number in a rational for which would be 312/24. This proves that it is a rational number.
Hello from MrBillDoesMath!
Answer:
(g o f)(0) cannot be evaluated
Discussion:
(g o f)(0) = g ( f(0)) if it exists but f(0) is not defined (as division by zero is not defined) so
(g o f)(0) cannot be evaluated
Thank you,
MrB
