Jacob and michael each build a model house for their house for their pet hamsters as shown below. jacob thinks that the house he built is larger than michael's, but michael thinks they are exactly the same size. who is correct?

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

you should think about the answers you give and expect the same form your questions.

what is the problem ?
