# Relations And Functions

In this discussion, you will be assigned two equations where you will  complete a variety of math work related to mathematical functions. Read  the following instructions in order and view the example (available for download in your online classroom) to complete this discussion. Please complete the following problems according to your assigned number. (Instructors will assign each student their number.)

my number is 34

first problem  h(x) = | −2x |

second problem  y = 2 ( x + 4)^2 – 3

There are many ways to go about solving math problems. To solve this  problem, you will be required to do some work that will not be included  in the discussion point.

• First, graph your functions so that you can clearly describe the  graphs in your post. Your graph itself is not required in your post,  although a 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.
• 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.
• Function
• Relation
• Vertical Line test
