Erik transformed the equation y = 2(x 2)^2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.y = 2(x 2)^2 + 5y = 2(x^2 4x + 4) + 5y = 2x^2 8x + 8 + 5y = 2x^2 8x + 13 A. No. The error is in the second line: the expanded form of (x 2)^2 is x^2 4. B. No. The error is in the third line: the product of 2 and x^2 4x + 4 is 2x^2 4x + 4. C. No. The error is in the fourth line: the sum of 8 and 5 is 12. D. Yes. Erik is correct in his transformation from vertex form to standard form.
