Domain: all real numbers 

What is domain and range? 

• Domain: The set of all possible input values (x-values) for which a function is defined. 

• Range: The set of all possible output values (y-values) that a function can produce. 

Is my equation a function? 

Yes, my equation is a function because if you draw a vertical line down the graph it would only touch the line once. 

Self Assessment  

1.  A time where i demonstrated the same idea twice was when i said the domain was all real number and when i said my equation is a function. 

2. I used my mathematical vocabulary when I was explaining the domain and range, i used it by showing that domain was X and range was Y and explaining its a function. 

3. I used formatting during this assignment when I put the title in the middle, When I numbered the last questions, when I put a title for each group of questions, and when I made important things bold
