Equation from Parabola

What is the equation of this parabola?

• y = (x - 1) (x - 5)

• y = (x + 1) (x + 5) 

• y = (x - 1) (x + 5) 

• y = (x + 1) (x - 5) 

What is the equation for this parabola?

What is a possible equation for this parabola?

• y = x (x + 5)

• y = (x + 5)²

• y = -x (x - 5)

• y = -x (x + 5)

Determine the solutions of the graph:

• y = (x + 3) (x - 1)

• y = (x + 3) (x + 1)

• y = (x - 3) (x - 1)

• y = (x - 3) (x + 1)
