SAT Math· difficulty 4/5

Convert y=−2x2+4x+1y = -2x^2 + 4x + 1 to vertex form.

  • A

    y=−2(x−1)2−3y = -2(x-1)^2 - 3

  • B

    y=2(x−1)2+3y = 2(x-1)^2 + 3

  • C

    y=−2(x−1)2+3y = -2(x-1)^2 + 3

    check_circle
  • D

    y=−2(x+1)2+3y = -2(x+1)^2 + 3

Explanation

y=−2(x2−2x)+1=−2(x2−2x+1)+2+1=−2(x−1)2+3y = -2(x^2 - 2x) + 1 = -2(x^2 - 2x + 1) + 2 + 1 = -2(x-1)^2 + 3.
