5. Evaluating Functions
For the function 𝐟 𝐱 = 𝟐𝒙 𝟐 +𝟑, find the following:
f(2) f(-1) f(7) f(-3)

6. Solving Quadratics (4t + 1) (t – 2 )=0 𝟒𝐝 𝟐 +𝟏𝟔=𝟏𝟔
Solve the following Quadratics
(4t + 1) (t – 2 )=0 𝟒𝐝 𝟐 +𝟏𝟔=𝟏𝟔

7. More Solving Quadratics
Solve the following Quadratic Function
𝑥 2 +8𝑥+15= 𝑥 2 −21𝑥=18

8. Transformations
Identify the transformations that need to be applied to the graph of the parent function 𝐲= 𝒙 𝟐
𝒚= 𝒙 𝟐 +𝟏𝟎 𝐲= 𝒙 𝟐 −𝟕
𝐲= 𝟏 𝟑 𝒙 𝟐 +𝟐 𝒚= −𝟑𝒙 𝟐 - 5

9. More Transformations
Write the equation of the function described by each of the following transformations of the graph of 𝐲= 𝒙 𝟐
Translated up 15 units
Stretched vertically by a factor of 6 and translated down 7 units
Reflected over the x – axis, shrunk vertically by a factor of 𝟏 𝟒 and translate up 9 units

10. Finding the Vertex Max/ Min
Find the coordinates of the vertex of the graph y= −2𝑥 2 − 8. Identify the vertex as a maximum or minimum.

11. Graphing Quadratic Functions

12. Quadratic Word Problem
Suppose you throw a baseball into the air with an initial upward velocity of 29 ft/s and an initial height of 6 ft. The formula h = -16t t + 6 gives the ball’s height h in feet at time t in seconds.
How high was the ball tossed?
How long did it take to get that high?
