Intro to Graphing Quadratics

What is the equation for the axis of symmetry?

• y=3

• x=3

• x=5

• x=1

What is the green dot on the parabola called?

• vertex

• minumum

• roots

• zeros

Find the y-intercept of f(x) = 2x² - 2x + 1

• (0, 2)

• (0, -2)

• (0, 1)

• (0, -1)

The axis of symmetry line passes through which point?

• y-intercept

• any random point

• vertex

• none of these

What are the x- intercepts?

• x= 0 and x= -4

• x= 0 and x= 4

• y= 0

• x= 2

Does this parabola have a minimum or maximum and what is its value?

REMEMBER MAXIMUM IS THE HIGHEST AND MINIMUM IS THE LOWEST.

• minimum: (5, 2)

• maximum: (5, 2)

• minimum: (2, 5)

• maximum: (2, 5)

If the a value is positive, which direction does the graph open?

• up

• down

• left

• right

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

• y = mx + b

• y = ax² + bx + c

Identify the 'a' value: y = 16x² -8x -24

• 16

• 8

• -8

• -24

Solve by factoring (find the x-intercepts)

x² + 13x + 12 = 0

• x = -12, -1

• x = 12, 1

• x = 13, 1

• x = -13, -1
