Introduction to Quadratics

What are the green dots called?

• axis of symmetry

• vertex

• parabola

• roots or x-intercepts

Which of the following equations matches standard form of a quadratic?

• ax + by = c

• y = a(x - h)² + k

• y = ax² + bx + c

• y = mx + b

How many solutions does this graph have?

• one

• two

• no solutions

• cannot be determined

What is the formula to find the vertex of a parabola?

• x = -b/2

• x = -b

• x = -b / (2a)

• x = -b / 2

What is the vertex of the quadratic function:
y = x² - 6x + 11?

• (3,2)

• (-3,-2)

• (-3,2)

• (3,-2)

In the Quadratic Equation 10x² - 4x + 5 = 2, what is the value of b?

What is the green dot on the parabola called?

• maximum

• minumum

• roots

• zeros

What is the maximum/minimum of a parabola called?

• vertex

• point

• top

• bottom

What is the vertex of a parabola?

• The max or min

• The point the line of symmetry goes through

• The point that is the same distance from both x-ints

• All of the above

What is the relationship between the vertex and the x-intercepts?

• the vertex is in the middle

• the vertex is closer to one of them

• the vertex is the same distance from both points

• There is no special relationship
