Question

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

Answer 1

Answer:

Option 1

Step-by-step explanation:

You can tell if a function is even if $f(-x)=f(x)$:

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

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

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

Since $f(-x)\neq f(x)$, the function is not even. Therefore, option 1 is the best option.
