• ### 1.1.1 Function notation

This is a preview. There are 3 more flashcards available for chapter 1.1.1

• #### Height is a funcation of age

Means h is  f of a
h=f(a)
h(a)
• ### 1.1.6 Evaluating and solving a graph

This is a preview. There are 2 more flashcards available for chapter 1.1.6

• #### Solving a funcation equation using a graph

Requires taking the given output and looking at the graph to determine the corresponding input
• ### 1.1.7 Formulas as functions

• #### Define(express) relationship using formulas

Express the relationship 2n+6p=12 as a function p= f(n)

soln:
2n+6p=12
2n-2n+6p=12-2n
6p=12-2n
6p/6=12/6-2n/6
p=f(n)= 2-2/3n
• ### 1.1.8 test of knowledge of all the topic dicuss in this section

• #### Example 12 given the funcation h(p)=p^2 +2pa) evlaute h(4)b) slove h(p)=3

Slon
a) h(4)= p^2+2p
= 4^2 +2(4)
= 16  + 8
= 24

b) h(p)=3
3= p^2+2p
-3+3=p^2 +2p-3
0=P^2+2p-3
factor it  x^2 -y^2= (x+y)(x-) so
0= (p-3)( p+1)

then 0=p-3    & 0=p+1
p=-3          p=1

h(p)=p^2+2p
3=-3^2+2(-3)
3=9-6
3=3
• ### 1.2.1 Notation

This is a preview. There are 2 more flashcards available for chapter 1.2.1

• #### Notation 9 interval notation

This is one way to describe intervals of input and output values, but it not the only way.

other ways
• inequality
•    set builder notation
• #### Inequlity, set buider notation, interval notaion

The value of h is greater than 5 and less than or equal to 10
• #### To combine two intervals together, using inequalities or set-builder notation, w

We can use  the word or. In interval notation, we use the unione use the union symbol, U  to combine two concentrated intervals together
• ### 1.2.2 Domain and Range from graph
