- y = x² + 4x + 5
- y = -x² - 4x + 9
- y = -x² + 4x + 5
- y = -x² - 4x + 5
Luz keeps a table for a bowl design. Which equation makes this table?
- y = x² - 2x - 6
- y = 2x² - 4x - 8
- y = 2x² + 4x - 6
- y = 2x² - 4x - 6
Milo keeps a table for a frog's hop (the frog keeps hopping off the page). Which equation makes this table?
- y = -2x² + 8x - 5
- y = -2x² - 8x - 5
- y = -x² - 4x - 5
- y = 2x² + 8x - 5
Pia graphs a fountain's arc on a grid. Which equation makes this graph?
- y = -2x² - 4x + 1
- y = -2x² + 4x + 1
- y = 2x² - 4x + 1
- y = -x² + 2x + 1
Ren graphs the inside of a mixing bowl on a grid. Which equation makes this graph?
- y = 3x² + 6x - 4
- y = x² + 2x - 1
- y = 3x² + 6x - 1
- y = 3x² - 6x - 1
Tala graphs a basketball shot on a grid (swish!). Which equation makes this graph?
- y = -3x² + 12x - 7
- y = -3x² - 12x - 7
- y = 3x² + 12x - 7
- y = -x² - 4x - 7
