11 Math Function Transformations Assignment Name: Jocelyn Witteveen

Grade 11 Math Project Day Assignment

Find out what the following manipulations of a, k, d, and c do. Be sure your results are true for all of the functions.

1. What happens when c is greater than zero? Less than zero? When c is manipulated, is it the Domain (x-values) or Range (y-values) being affected compared to the original graph?
When c is greater than zero, the graph moves up on the y-axis. When it’s less than zero, it moves down on the y-axis. C is the y-value at the start, vertex, or asymptote of the graph. The Range is being affected because c changes the y of the graph.

2. What happens when d is greater than zero? Less than zero? When d is manipulated, is it the Domain …show more content…

When it’s less than zero, it moves left on the x-axis. D is the x-value with the opposite positive/negative sign at the start, vertex, or asymptote of the graph. The Domain is being affected for the radical and rational function because d changes the start of the graph on the x-axis. The Domain stays the same for the quadratic and absolute functions because they continue for infinity in both directions of the x-axis.

3. What happens when a is positive? What happens when a is negative? When a is manipulated, is it the Domain (x-values) or Range (y-values) being affected compared to the original graph? When a is positive, the graph opens up, into positive y-values (if c is at zero). When it’s negative, it opens down, into negative y-values (if c is at zero). A will determine whether the graph will open up or down, depending on if it’s positive or negative. For the rational function, when a is positive, it stays in the top right and bottom left planes (quadrant 1 and 3). When a is negative, it goes to the opposite planes (quadrant 2 and 4). The Range is being affected because a changes whether the graph will open up or

1.1.2 Graphs We have now converted information from words or pictures to tables to formulae and now we’re going to look at how we can convert information into graphs: Example: If we invest R1 and it doubles every month, how much will we have at the end of 1 year? Let’s first draw a table: Months 1 2 3 4 5 6 7 8 9 10 11 12 Rands 1 2 4 8 16 32 64 128 256 512 1024 2048 Now let’s depict this information as a graph or chart: We can draw a bar chart:

Homeroom Reflection Junior year I have grown as a student this semester by watching the mala movie. This has helped me grow as a student because it showed me how just one voice can change so much in a community. From this experience I learned how Mala was an ordinary girl but who ones spoke up for what she believed was right for her community and the people all around her. After she started to change her community on a positive way for example, have more schools so students can have an education and making sure girls were able to attend school more often. Therefore, when she spoke up for what she thought was right and changed people 's life there was some who didn 't appreciate what she was doing so decided to shot her and ended up shooting her on her forehead.

This is also where price mechanism takes place because any changes in demand and supply, will affect the price, and eventually balancing the demand to be equal to supply. This is the reason why consumers and producers have no control over the price, and in this situation, everyone is considered as price takers. This causes a horizontal line in the demand curve for the firm’s product(s), as can be seen in Figure 1 (b). Figure 1 There are barely any barriers to enter this market, making it easy to enter and exit according to the firm’s capabilities.
