Which quadric rule represents the data in the table below?
A. y=-2x^2+5
B. y=-x^2+5
C. y=x^2-5
D. y=x^2+5
@Summer we need the data to figure it out kiddo
oh im sorry, I will post them @Mrs. Matthew.
x= -1, 0,1,2,3
y= 6,5,6,9,14
Looks like D to me
To determine which quadratic rule represents the data in the table, we need to analyze the relationship between the x-values and the corresponding y-values. However, since you haven't provided the table, I can't directly determine the answer.
Nevertheless, I can explain the steps or techniques that can be used to identify the correct quadratic rule given a table of values. Here's what you can do:
1. Look for a pattern: Examine the x-values and their corresponding y-values. See if you can identify any patterns or trends in the data.
2. Create a system of equations: Use the provided x-values and y-values to create a system of equations in the form y = ax^2 + bx + c. Plug in the x-values from the table into the equation and solve for the coefficients a, b, and c. This will help you determine the form of the quadratic rule.
3. Test the quadratic rules: Once you have determined the quadratic rule in the form y = ax^2 + bx + c, substitute the x-values from the table into each quadratic rule and calculate the corresponding y-values. Compare these calculated y-values with the actual y-values from the table to find the best match.
By following these steps, you should be able to determine which quadratic rule best represents the data in the table.
