Quadratic Graphs Equations

What is the equation of the quadratic in the graph?

• y = (x+1)(x-2)

• y = (x-1)(x+2)

• y = (x+.5)² - 2.25

• y = (x-.5)(x-2)

What is the equation of the quadratic function in the graph?

• y = x² - 2x - 8

• y = x² + 2x + 8

• y = x² - 2x + 8

• y = x² + 2x - 8

What is the equation of the quadratic function in the graph?
