Advanced MathEasyParabola with vertex at the origin

Advanced Math practice question

Which of the following equations represents a parabola whose vertex is at the origin?

  1. A. y = 3x²Correct
  2. B. y = 3x² + 1
  3. C. y = (x − 1)²
  4. D. y = 3x

Answer: A. y = 3x²

y = 3x² has its lowest point at (0, 0).

Why the other answers are wrong

B. y = 3x² + 1
The vertex is at (0, 1).
C. y = (x − 1)²
The vertex is at (1, 0).
D. y = 3x
This is a line, not a parabola.
