The correct option regarding whether the equation x² = y² is a function is:
No, since if you solve the equation for x, then
<h3>What is needed for a relation to represent a function?</h3>
In a function, each value of x can be associated with only one value of y.
In this problem, the equation is:
Then:
x is associated with two values, and , hence it is not a function.

Answer: 31%
Step-by-step explanation:
Formula : Percent of the variability =
, where = Coefficient of Determination.
SSR = sum of squares of regression
SST = total sum of squares
is the proportion of the variation of Y that can be attributed to the variation of x.
As per given , we have
SSR = 14.55
SST= 46.8
Then, the percent of the variability in y that can be explained by variability in the regression model =
Hence, the percent of the variability in y that can be explained by variability in the regression model = 31%
