Question 4 • [INMT3] Integrated Math 3 Sem 1 (26-27)

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

Answer

A

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

B

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

C

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

D

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

Explanation

To test whether a function is even, substitute −x for x and check whether f(−x) = f(x). Here, f(−x) = (−x)² − (−x) + 8, so compare that expression with x² − x + 8. This is the method stated in choice B.
