Quadratic Features and GCF

What are the values of a, b, and c in the quadratic equation 3x² + 4x - 10 = 0

• a = 3x² b = -10 c = -4x

• a = 3 b = -10 c = -4

• a = 3 b = -4 c = -10

• a = 3 b = 4 c = -10

Which value is the vertex?

• (-4, 0)

• (-1, -9)

• (0, -8)

• (2, 0)

What is the equation for the axis of symmetry?

• x = b / 2

• x = 2a / -b

• x = 2 / b

• x = -b / 2a

How do I find the y-value of the vertex?

• factor

• x = -b / 2a gives you the y-value of the vertex

• find x = -b / 2a and then plug in for x and solve for y.

• find -b / 2a and then plug in for y and solve for x.

What do we call the highest or lowest point of a quadratic?

• parabola
• vertex
• graph
• point
