1
1. Warmup: Review quiz from yesterday
2. Finish the Functions task card activity
3. Start reading the examples about realworld scenarios and the
functions that can represent them. We can compare functions using
graphs, tables, equations, and verbal descriptions.
4. Desmos Graphing Stories activity!
5. iXL skills for this week: Z.1, Z.2, Z.3, and I.1 due
tonight.

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.
1)
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
