Transcript

  • 1. Opener: Evaluate each of the following expressions for x=5. 1.) 3x + 6 2.)  3.) x2 +4 1
  • 2. 3.24 & 3.25 An Introduction to Function Notation Think Back  shhhh.....just think!  Think of a linear equation that you have seen this year.   Now, write down your equation. How many solutions are there to this equation? Graphing on the  Graph your equation on the Nspire. Nspire On the calculator we said f(x) meant the same thing as  what ? Why does it say f1 (x) = .....? How will we represent different functions on paper? 2
  • 3. Topic One: Function Basics (Ex. 1) Find f(4) if f(x)= 3x+6. (Ex. 2) Find g(13) if g(x)=  Think‐ Pair‐ Share (Ex. 3) Find h(7) if h(x)=x2+4. (Ex. 4) Find f(‐2) if f(z)= |3z + 1| (Ex. 5) Find f(      ) if f (p) = 4(p ‐ 2). 3
  • 4. Topic Two:  Input‐Output Values (Ex. 6) Given the function f(x) = x4 ‐ 5 and our knowledge  about exponents, label which column you think is the  input and which is the output. What value belongs in the third input box?  How might  we solve for that value? If we were given the input value instead, how would we  solve for the output value? It's Your Turn! Use the function f(x) = ‐2x + 5 to complete the table  (Ex. 7) with your partner. 4

  • 6. Exit Slip: I need your help to come up with a STELLAR opener for  Design an Opener. next class. With your group, please write 2 questions that can be  used as an opener in future classes.  These questions  should review topics we discussed today: basic  evaluation of functions and problems dealing with  input‐output values of functions.  The questions may be  similar in nature to what we did today, or may challenge  your classmates beyond the scope of today's lesson. Remember that I will be collecting these, and they will  serve as a part of your group assignment grade.  6
