Blue packet ­ textbook pages when done  with functions task card activity 
Make sure to read the examples
Complete Got It? Questions Work on Independent Practice

When done with Quizizz, please go to desmos.com
Click on Start Graphing Please graph y=4x and y=    x Copy the 2 equations on your paper.  Which one is  steeper?  Look at the coefficient or constant of  proportionality or k value for both.  What do you notice?
Relate the k value to the steepness.  Write:
The steeper the slope, ______________________
Note how the lines go on forever in both directions.

2) Erase previous graphs and graph
  y=4x and y= x^2     (This is how you enter y=x  ) Copy the 2 functions on your paper.  Which one is linear? 
Note the curve of the parabola.  When you are finishing your task  activity, revisit your graphs for parabolas.  There should be no  sharp angles in your drawings.
3)  Erase previous graphs and graph
y=       + 2      Is it linear?  Where does it intersect the y­axis?
What is the slope or rate of change?
4)  Erase previous and graph:
y = 3
This is an exponential functions that represents the spread of the  corona virus, given a basic reproduction number of 3 (1 person  infects 3), and wave number x.
If 28000 have been infected as of 2/6/20, what is x?

A rule that assigns to each input exactly one output.  The graph of  a function is the set of ordered pairs consisting of an input and the  corresponding output.
Independent variable ­ variable of choice, that  can change 
Dependent variable ­ depends on or responds to  the independent variable 
Controlled variable ­ quantities that we keep  constant during an experiment
