high school easy linear function hw (part3)

high school easy linear function hw (part3). Part 3: Discussion Questions: All answers should be complete sentences and include
units.
1. Explain why linear functions are appropriate to represent these toys.
2. Why is the relevant domain different from the usual domain of a linear function?
3. Look at both Upper compartment functions, what physical quality of the toy is
represented by the vertical intercepts?
4. Suppose we have two new toys, Toy A and Toy B, and their function equations for the
upper compartments are ?(?) = 16 − 3? and ?(?) = 8 − 3?, compare the vertical
intercepts of these new functions and thoroughly explain what they tell you about the
toys? (Be specific and include units in your explanation.)
5. Look at both Lower compartment functions. What physical quality of the toy is
represented by the vertical intercepts? Explain.
6. Continue looking at both the Lower compartment functions, what quality of the timer is
represented by the slope? (Be specific and include units in your explanation.)
7. Suppose we have two new toys, Toy C and Toy D, and their function equations for the
lower compartments are ?(?) = 3? and ?(?) = 9?. Compare the slopes of these new
functions and explain what they tell you about the two toys. (Be specific and include units
in your explanation.)
8. Does this same observation about slope hold true for the Upper compartment functions?
If one toy has a larger slope than the other, what does it mean?
Hint: Remember what it means to be a larger number when you are dealing with
negatives. Is -5 larger than -2 or is -2 larger than -5? Use this idea in your explanation.
