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 +

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

Step-by-step explanation:

to know if a function is even, it has to be symmetric with respect to the y-axis. this means we need to plug in -x wherever we see x, and if we get the same answer, then it is an even function

for f(x) = x² - x + 8, we need to solve when f(x) = f(-x)

f(-x) = (-x)² - (-x) + 8

f(-x) = x² + x + 8

f(x) = x² - x + 8 is not an even function, as its not equal to f(-x).

the statement that best matches what we did here is B
