The graph of y=f(x)y = f(x) is symmetric about the yy-axis. Which statement must be true?

  • A

    ff passes through the origin

  • B

    f(x)=f(x)f(-x) = -f(x)

  • C

    f(x)=f(x)f(-x) = f(x)

    check_circle
  • D

    ff has an inverse

Explanation

Symmetry about the yy-axis means ff is even: f(x)=f(x)f(-x) = f(x).
