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