Solution

Let's graph the function given the table of values. The function provided, which appears to be y=x2+3y = x^2 + 3, has the corresponding table of values:

Table of Values:

xxyy
-10103
-984
-867
-752
-639
-528
-419
-312
-27
-14

312
419
528
639
752
867
984
10103

To plot at least five points from this table, you can select five values of (x,y)(x, y). Here are some recommended points to plot:

  1. (5,28)(-5, 28)
  2. (3,12)(-3, 12)
  3. (0,3)(0, 3)
  4. (3,12)(3, 12)
  5. (5,28)(5, 28)

Plotting the Points:

  1. Start by marking the x-axis and y-axis on the graph.
  2. Plot the points (5,28)(-5, 28), (3,12)(-3, 12), (0,3)(0, 3), (3,12)(3, 12), and (5,28)(5, 28) on the graph.
  3. Connect these points smoothly to form the parabolic shape of the function y=x2+3y = x^2 + 3.

Graph Characteristics:

  • The graph is a parabola opening upwards, shifted 3 units up from the standard position of y=x2y = x^2.

Would you like a detailed graph of this function, or do you have any specific questions about plotting these points?

Follow-Up Questions:

  1. What happens to the graph if you change the constant value in the function?
  2. How would the graph look if the function were y=x2+3y = -x^2 + 3?
  3. What is the vertex of the parabola represented by this function?
  4. How does changing the coefficient of x2x^2 affect the width of the parabola?
  5. How can you determine the symmetry of the graph based on its function?

Tip:

To quickly identify key points on a parabola, always start with the vertex and symmetry points around it!
