My Equation:

Demsos Graph:

A Demsos graph is a graph that we can graph equations and plot data points. We used the Desmos.com website to make our graphs. This is my graph below of my equation.

Domain of My Graph:

The Domain of my graph is x is greater or = to zero

Ordered Pairs: (0,0), (1,1), (4,2), (9,3), (16,4)

Mapping Diagram:

What do the Domain and Range mean?

The domain of my graph represent the x axis values on my graph and the range represents the y axis values.

Function or Not?

My graph is a function because when I use the vertical line test, my graph intersects at the most one time which means it is a function. If a vertical line crosses over twice it’s a non-function.

Also in my mapping diagram if every input has exactly one arrow pointing away from it, it is a function. If one of the inputs has no arrow pointing away from it, it’s not a function.

Self Assessment

1. An example from the assignment where I represented the same mathematical idea in multiple ways was when I showed what my equation was, graphed my equation and used mapping notation to show the domain and range of my equation.
2. I used mathematical vocabulary when I explained what the domain, range and function of my graph were which are math terms.
3. I used formatting in my assignment when I chose to use clear font that was easy to read. As well I made my headings of each topic in bold font so it was clear to the reader. I also numbered my questions so it was easier for the reader to understand which questions I was answering.
