Which equation matches the info: vertex at (5,-2)

Which equation matches the info: x-intercepts at (2,0) & (-4,0) and goes through (3,14)

Which equation matches the info: x-intercepts at (-3,0) & (7,0)

Convert the equation from vertex form (shown) to standard form:

• y = 9x² - 15x + 21

• y = -3x² - 75x - 4

• y = 9x² + 90x + 221

• y = -3x² - 30x - 79
