Does the following quadratic equation have a maximum or minimum value? How can you tell?

y = x² + 2x - 3

• Minimum value, because the a value is positive

• Maximum value, because the b value is positive

• Maximum value, because the a value is positive

• Minimum value, because the c value is negative

Which quadratic equation models the parabola shown?

• y = (x - 2)(x + 5)

• y = (x + 2)(x + 5)

• y = -(x - 2)(x - 5)

• y = -(x + 2)(x + 5)

What is the equation of this graph in intercept form?

• y = 2(x + 3)(x - 1)

• y = 2(x - 3)(x + 1)

• y = -2(x - 3)(x + 1)
