Prоve the fоllоwing stаtement using а proof by cаses. [Hint: there are 3 cases] “For all positive integers n ≤ 3, n! ≤ n2+1 ." Use good proof technique. Grading rubric:1 pt. State any givens and assumptions.3 pt. Clearly identify the cases and prove each case.1 pt. State the final conclusion at the end of the proof. Note: Remember that n factorial, written as n!, is defined as n(n-1)...(2)1, the product of n times every positive integer less than n. To avoid the need for typing superscript exponents, you may use the expression ‘n-squared’ or ‘n^2’ to represent n2. Also the ≤ symbol can be written as
