Given the following list of numbers: 90 8 7 56 123 235 9 1 653 trace the execution for: (a.1) selection sort (only the first 5 steps) (a.2) mergesort. (b) given the following list of numbers: 3 1 4 1 5 9 2 6 5 3 5 trace the execution for quicksort with median-of-three partitioning and a cutoff of 3.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

the answer would be c
