Mat222 week 5 DQ

In this discussion, you will be assigned two equations with which you will then do a variety of
math work having to do with mathematical functions. The following two equations are my given
equations based on the last letter of my last name “R”
20. y = | x − 1 | + 2

54.

There are many ways to go about solving math problems. For this assignment you will be
required to do some work that will not be included in the discussion. First, you need to
graph your functions so you can clearly describe the graphs in your discussion. Your
graph itself is not required in your post, although the discussion of the graph is required.
Make sure you have at least five points for each equation to graph. Show all math work
for finding the points.

•

Specifically mention any key points on the graphs, including intercepts, vertex, or
start/end points. (Points with decimal values need not be listed, as they might be found in
a square root function. Stick to integer value points.)

•

Discuss the general shape and location of each of your graphs.

•

State the domain and range for each of your equations. Write them in interval notation.

•

State whether each of the equations is a function or not giving your reasons for the
answer.

•

Select one of your graphs and assume it has been shifted three units upward and four
units to the left. Discuss how this transformation affects the equation by rewriting the
equation to incorporate those numbers.

Incorporate the following five math vocabulary words into your discussion. Use bold
font to emphasize the words in your writing (Do not write definitions for the words;
use them appropriately in sentences describing the thought behind your math
work.):
o Function
o Relation
o Domain
o Range
o Transformation
Your initial post should be at least 250 words in length. Support your claims with examples from
required material(s) and/or other scholarly resources, and properly cite any references. Respond
to at least two of your classmates’ posts by Day 7.
