Which statement best describes how to determine whether f(x) = x2 – x + 8 is an even function?
determine whether –x2 – (–x) + 8 is equivalent to x2 – x + 8.
determine whether (–x)2 – (–x) + 8 is equivalent to x2 – x + 8.
determine whether –x2 – (–x) + 8 is equivalent to –(x2 – x + 8).
determine whether (–x)2 – (–x) + 8 is equivalent to –(x2 – x + 8).

Determine whether (–x)2 – (–x) + 8 is equivalent to x2 – x + 8.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
