Writing vertex form
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- x² first: y = x² − 6x + 5: vertex form
- −x² first: y = −x² + 6x − 5: vertex form
- a number in front of x²: y = 2x² − 12x + 7: vertex form
Sample Sheet · Level 1
- y = x² − 2x − 7: vertex form
- y = x² − 12x + 29: vertex form
- y = x² − 10x + 28: vertex form
- y = x² − 2x + 6: vertex form
- y = x² − 10x + 17: vertex form
- y = x² − 12x + 33: vertex form
- y = x² + 8x + 19: vertex form
- y = x² − 6x + 4: vertex form
Answer key
- y = (x − 1)² − 8
- y = (x − 6)² − 7
- y = (x − 5)² + 3
- y = (x − 1)² + 5
- y = (x − 5)² − 8
- y = (x − 6)² − 3
- y = (x + 4)² + 3
- y = (x − 3)² − 5
Sample Sheet · Level 3
- y = x² + 10x + 24: vertex form
- y = x² + 12x + 43: vertex form
- y = −x² − 16x − 69: vertex form
- y = −2x² + 4x − 6: vertex form
- y = 3x² − 30x + 78: vertex form
- y = −x² − 14x − 57: vertex form
- y = −x² + 10x − 33: vertex form
- y = −2x² − 16x − 27: vertex form
Answer key
- y = (x + 5)² − 1
- y = (x + 6)² + 7
- y = −(x + 8)² − 5
- y = −2(x − 1)² − 4
- y = 3(x − 5)² + 3
- y = −(x + 7)² − 8
- y = −(x − 5)² − 8
- y = −2(x + 4)² + 5
