P.O.C

How do i determine what the graph will look like bu the equation?

NOTES:

graph the function, state domain, and range, and write the ordered pairs.

f(x)= -2sqrt x-4

x y

4 0

8 -4

5 -2

STEPS:

1- write equation

2-plot point

3-reflect over x axis

how would i express the domain and range in interval notaiton

graph state domain range

f(x)=sqrt x^2-16

x y

4 0

5 9

D; (-infinity,-4] U [4, infinity)

R: [0,infinity)

1-find the x int

2-plug into graph

3-graph

4-find domain and range

reflection: today we went over how to find the domain and range. and we were abole to graph our outcomes on desmons and realized we did something wrong. One pf our problems though contained two equations. we had to insert our points in interval notation.

POC:

how do i find the coordinate for 7pie

3

NOTES:

Find the exact value of the trig functionat the given real number

a.) cos 7pie

3

5Pie over 3 + 2pie over 3= 7pie over 3= 1/2

b.) sec 7pie = 2

STEPS:

qrite question

Reflection:

today we went over the tricks to fill in the unit cirl. for the radians you need to go from 6, 4, 3, 2 and copy it over, the six needs to be closer to the x axis. then the quadrent 2 you subtract 1 from the denominator to get the numerator. for quad 3 you add 1 and for quad 4 you add the two numbers following th eline to quad 2.
