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?

A.) The student's claim is true, because for any input of x, f(x)=f(−x).
B.) The student's claim is not true, because for any input of x, f(x)=f(−x).
C.) The student's claim is true, because for any input of x, f(x)=−f(x).
D.) The student's claim is not true, because for any input of x, f(x)=−f(x).
