If f(x) = (xm + 9)2, which statement about f(x) is true?
a: f(x) is an even function for all values of m.
b: f(x) is an even function for all even values of m.
c: f(x) is an odd function for all values of m.
d: f(x) is an odd function for all odd values of m.

I believe the correct answer from the choices listed above is option A. If f(x) = (xm + 9)2,  then f(x) is an even function for all values of m. The reason of that is because no matter what m is, assuming it is an integer 2m will always be an even number. Hope this answers the question. Have a nice day.
