PLEASE HELP

A student says that the function f(x)=3x4+5x2+1 is an even function. Is the student's statement true or not true, and why?

1) The student's claim is not true, because for any input of x, f(x)=−f(x).
2) The student's claim is not true, because for any input of x, f(x)=f(−x).
3) The student's claim is true, because for any input of x, .f(x)=−f(x).
4) The student's claim is true, because for any input of x, f(x)=f(−x).
