Quadratics Introduction

What is the domain of the function?

• x > 2

• x > 3

• All Real Numbers

What is the range of the quadratic function?

• All Real Numbers

Is this graph linear?

• Yes

• No

• x=6 & x=5

• x=2 & x =3

• x=2 & x=-3

• x=-2 & x=3

Solve (x-1)(x-2) =1

• x=0 & x= 3

What is the arrow pointing at? How can you use this value?

• The arrow is pointing at the y-intercept. The x-value is the axis of symmetry and the y-value of this point is equivalent to the maximum/minimum 

• The arrow is pointing at the vertex. The x value of this point is equivalent to the maximum/minimum and the y-value is the axis of symmetry

• The arrow is pointing at the solution. The y value of this point is equivalent to the maximum and the x value is equivalent to the minimum

• The arrow is pointing at the vertex. The x-value is the axis of symmetry and the y-value is equivalent to the minimum/maximum

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

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

• (3,2)

• (-3,-2)

• (-3,2)

• (3,-2)

Is this a max or min?

• max

• min

• cannot be determined
