• y = 6x² +16x -3

• None of these

Rewrite y = 8(x -3)² - 15 in standard form

• y = 8x² - 24x + 57

• y = 8x² + 57

• y = 8x² - 6x + 57

• y = 8x² - 48x + 57

Rewrite y = x² + 12x + 7 in vertex form

• y = (x+6)² + 7

• y = (x+6)² + 43

• y = (x+6)² - 29

• None of these

Rewrite y = x² - 16x + 12 in vertex form

• y = (x - 8)² + 76

• y = (x - 16)² + 76
