Note from the author:
A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Solve It! Response & Explanation

1.

Problem 1 Got It?
Graph the parent square root function and the two translations in the same plane.
Notice how the translations relate to the parent function, to their graphs, and to one another.
Zoom and pan your graph to establish an appropriate viewing window.

Problem 4 Got It? You can model the population P of Corpus Christi, Texas, between the years 1970 and 2005 by the radical function below.
Using this model, in what year was the population of Corpus Christi 275,000?

The Desmos graphing utility is embedded below for your convenience.

Problem 5 Got It?
Graph the parent cube root function and the translation in the same plane.
Notice how the translation relates to the parent function and to its graph.
Zoom and pan your graph to establish an appropriate viewing window.

8.

a. Sketch a graph of the function using the blue pen tool on the canvas below.
b. Graph the function using the embedded Desmos graphing calculator above.
c. Sketch a new (more accurate?) graph of the function in red on the same plane as your blue sketch.

It is okay if your blue and red graphs overlap.
As always, label the axes and indicate thier scale by marking at least one value on each axis.

Review Lesson 6-7: Identify the inverse of each function on the right and state whether the inverse is also a function.

  • The inverse IS also a function.
  • The inverse IS NOT a function.
  • The inverse is:
