Station 1 – Graphing Quadratics For  each  of  the  following  questions,  find  the  vertex,  axis  of  symmetry,  and  y-­‐intercept.              

Station 2 – Writing Quadratics

1. Create  a  quadratic  function  in  standard  form  with  zeros  −7  and  2.    2. Create  a  quadratic  function  in  vertex  form  with  vertex  (2,−4).  

 3. Create  a  quadratic  function  in  standard  form  with  zeros  -­‐2  and  0.  

 4. Create  a  quadratic  function  in  standard  form  with  zeros  ±7𝑖.  

 5. Create  a  quadratic  function  in  standard  form  with  vertex  (−2,−18)  

and  y-­‐intercept  (0,−10).    

   

1. 𝑦 = −2 𝑥 − 2 ! + 5    vertex:  AoS:  y-­‐intercept:  

2. 𝑦 = −𝑥! + 4𝑥 − 3    vertex:  AoS:  y-­‐intercept:  

3. 𝑦 = −3𝑥! + 6𝑥 + 1    vertex:  AoS:  y-­‐intercept:  

4. 𝑦 = 𝑥 − 1 ! + 4    vertex:  AoS:  y-­‐intercept:

  Station 3 – Solving Quadratics Solve  the  following  using  any  method  of  your  choice.    You  MUST  use  each  method  one  time  –  QF,  factoring,  completing  the  square,  and  square  roots.       1.    x2  =  6x  –  11             2.    4x2  +  1200  =  0        

3.    p2  =  6p  –  20             4.    x2  =  12p  +  45    

               

  Station 4 –Quadratic Applications 1. The  length  of  a  rectanglular  piece  of  cardboard  is  2  less  than  3  times  its  

width.    If  the  area  measures  65  𝑚!,  find  the  length  of  the  rectangle.      

2. An  object  is  launched  into  the  air  from  a  ledge  at  an  initial  vertical  velocity  of  96  feet  per  second.    Its  height  H,  in  feet,  at  t  seconds  is  given  by  the  equation  𝐻 = −16𝑡! + 96𝑡 + 16  .      

a.  Find  all  times  t  that  the  object  is  at  a  height  of  160  𝑓𝑡.    

b. What  is  the  height  of  the  ledge?    How  do  you  know?      

3. The  height  in  feet  of  a  golf  ball  hit  into  the  air  is  given  by  ℎ = −16𝑡! + 64𝑡,  where  t  is  the  number  of  seconds  elapsed  since  the  ball  was  hit.  

a. What  is  the  maximum  height  of  the  ball?    How  long  does  it  take  to  reach  this  height?    

b. How  long  does  it  take  for  the  ball  to  hit  the  ground?    

c. Determine  all  values  of  𝑡  for  which  the  ℎ > 48.

1.   −84 + 36                                                                                2.    (3𝑖)(4𝑖)(−9𝑖)                                                                        

3.    −3 1   +  2𝑖 +  2𝑖 3 − 4𝑖        

4.     3 + 5𝑖 ! + 6 − 2𝑖 !  

5. Evaluate  𝑖!".      

Station 6 – Converting Quadratic Forms  1.    Convert  the  following  from  standard  to  vertex  form.       a.    y  =  x2  +  4x  –7       b.    y  =  x2  +10x  +5    2.    Convert  the  following  from  vertex  to  standard  form.       a.    y  =  (x  +  9)2  -­‐  3       b.    y  =  2(x  -­‐  5)2  +  12
