Solutions  Instructions: Use the resources located on the Weebly to answer the following questions.  

 Problem  1:  Define  the  following  vocabulary  terms.    

a.) Increasing:    To  grow  larger  or  greater;  enlarging.      

b.) Decreasing:  Becoming  less  or  fewer;  reducing.      

c.) Constant:  Not  changing;  remains  the  same.    

d.) Linear:  Straight  line.    

e.) Non-­‐linear:  Non-­‐straight  line;  curve.            Problem  2:  Consider  the  graph.  

 Describe  the  graph  by  writing  each  set  of  vocabulary  terms  into  the  corresponding  section  of  the  table.    •Constant            •Linear  and  increasing            •Non-­‐linear  and  decreasing            •Non-­‐linear  and  increasing    

 From  point  L  to  point  M:  Linear  and  increasing  

 From  point  M  to  point  N:  Non-­‐linear  decreasing  

 From  point  N  to  point  X:  Non-­‐linear  and  increasing  

 From  point  X  to  point  Y:  Constant

 Problem  3:     Solve:    𝑥! = 25.    

a.) The  equation  has  no  solutions.  b.) -­‐5  is  the  only  solution.  c.) 5  is  the  only  solution  d.) 5  and  -­‐5  are  both  solutions.    

 

Problem  4:     Simplify  the  expression  to  its  simplest  exponential  form:  !!

!!  =  𝟑𝟔  

   Problem  5:  Choose  all  the  expressions  that  are  equivalent  to  2! ∙ 2!.  There  may  be  more  than  one  equivalent  expression.    a.) 𝟐𝟐 ∙ 𝟐𝟐 ∙ 𝟐𝟑  b.) 4!"  c.) 4!!!  d.) 𝟐𝟕  e.) 2!"  

   Problem  6:  Write  12,350  in  scientific  notation.    𝟏.𝟐𝟑𝟓  ×  𝟏𝟎𝟒      Problem  7:  Approximately  1.2  ×  10!  gallons  of  water  flow  each  second.  There  are  3.24  ×  10!  seconds  in  1  day.  Select  the  approximate  number  of  gallons  of  water  that  flow  in  1  day.    (Hint:  How  do  you  multiply  two  scientific  notation  forms?)    a.) 38.88  ×  10!  b.) 𝟑.𝟖𝟖𝟖  ×  𝟏𝟎𝟔  c.) 388.8  ×  10!  d.) 3.888  ×  10!  

   Problem  8:  For  each  number,  decide  whether  the  following  are  rational  or  irrational.    

a.) !!  =  Rational         c.)  𝜋  =  Irrational  

 b.) 2  =  Irrational         d.)  −27  =  Rational

 Problem  9:  Describe  a  sequence  of  transformations  from  the  original  figure  to  the  new  figure.    

 The  original  figure  translated  6  units  horizontally  and  reflected  over  the  x-­‐axis.  

   

Problem  10:  Translate  the  image  4  units  vertically  and  1  unit  horizontally.  Then  reflect  the  image  across  the  y-­‐axis.
