Find the median for the data items in the given frequency distribution.

2,5

Step-by-step explanation:

Median = middle number

= 1,2,6,8,4,5,3,7

median = 8 & 4

= 3 & 2

= (3+2) /2

= 5/2

= 2,5

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
