If f(x) = (x + 9)?, which statement about f(x) is true? f(x) is an even function for all values of m.
f(x) is an even function for all even values of m.
f(x) is an odd function for all values of m.
f(x) is an odd function for all odd values of m.

I think the Answer is "f(x) is an even function for all even values of m."

Step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
