  1.  
    1. What are the coordinates of the red dot in the graph shown? Answer

    2. What is the domain and range of the section of the graph shown? Answer

       
      This is the graph of the linear function y = 0.8x + 2.

  2.  
    1. What are the coordinates of the red dot in the graph line shown? Answer

    2. What are the domain and range of only the section of the parabolic graph shown? Answer

    3. If this graph were extended indefinitely, how would this change the domain and range?

       
      This is the graph of quadratic function of y = (x - 2) squared + 3.

  3.  
    1. What are the coordinates of the red dot in the graph shown? Answer

    2. What is the domain and range of only the section of the graph shown?

       
      This is the partial graph of the quadratic Function y = (x + 4)squared - 9. There is a red point at the vertex of the parabola.
