SAT Math· difficulty 4/5

The graph of f(x)=x2f(x) = x^2 is reflected over the x-axis and shifted up 5. What is the new equation?

  • A

    y=(x5)2y = (x-5)^2

  • B

    y=x2+5y = x^2 + 5

  • C

    y=x2+5y = -x^2 + 5

    check_circle
  • D

    y=x25y = -x^2 - 5

Explanation

Reflect over x-axis: y=x2y = -x^2. Shift up 5: y=x2+5y = -x^2 + 5.
