Advanced MathEasyShifting a parabola upward
Advanced Math practice question
The graph of y = x² is shifted upward by 3 units. Which equation describes the new graph?
- A. y = x² + 3Correct
- B. y = (x + 3)²
- C. y = x² − 3
- D. y = 3x²
Answer: A. y = x² + 3
Adding 3 to every output moves the graph up by 3.
Why the other answers are wrong
- B. y = (x + 3)²
- This shifts the graph 3 units to the left.
- C. y = x² − 3
- This shifts the graph down.
- D. y = 3x²
- This makes the graph narrower, not higher.
