Interpret Quadratics

Is this a max or min?

• max

• min

• cannot be determined

The graph of a quadratic function is called a

• Parabola

• Vertex

• Axis of Symmetry 

• Vertex Form

Label the key features of the quadratic

e

f

d

line of symmetry

range

domain

y-intercept

vertex

x-intercept

Drag the functions into the correct column: does the parabola open upward or downward?

Groups:

(a) Upward

,

(b) Downward

• The ball hits the ground in 6.2 seconds.

• vertex

• Reaches a max of 164 feet in 3 seconds.

• x-intercept

• The ball is launched from 20 feet

• y-intercept

Solve Using the Quadratic Formula
 x² + 4x - 40 = -8

• -10 & -4

• -4 & 10

• -8 & 4

• 8 & -4

Use the quadratic formula to solve 2x² + 2x - 12?

• -2, 3

• 2, 3

• 2, -3

• -2, -3

In the equation
y = x² +5x +7, match each leading coefficient with its correct letter 

• a=0, b=5, c=7

• a=1, b=5, c=7

• a=7, b=5, c=1

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3
