Math Problem Statement

Copy and complete the table of values for y = x^2 + 8. What numbers replace A and B?

Solution

The question in the image asks for the completion of the table of values for y=x2+8y = x^2 + 8, specifically finding the missing values labeled AA and BB.

Steps to solve:

  1. Understand the function:
    The equation y=x2+8y = x^2 + 8 means you square the xx-value, then add 8 to find yy.

  2. Apply the given values:

    • For x=2x = -2:
      y=(2)2+8=4+8=12y = (-2)^2 + 8 = 4 + 8 = 12, so A=12A = 12.
    • For x=2x = 2:
      y=(2)2+8=4+8=12y = (2)^2 + 8 = 4 + 8 = 12, so B=12B = 12.

Completed Table:

xx-2-1012
yy1298912

Final Answer:

  • A=12A = 12
  • B=12B = 12

Would you like a detailed explanation or have further questions?

Here are five related questions to deepen understanding:

  1. What happens to yy as xx becomes more negative or more positive?
  2. How would the table change if the equation were y=x25y = x^2 - 5?
  3. Can you plot these points on a graph and describe the shape of the curve?
  4. What is the vertex of the parabola represented by y=x2+8y = x^2 + 8?
  5. How do you determine whether a quadratic opens upwards or downwards?

Tip: The constant in the equation (here, 8) determines the vertical shift of the parabola!
