Answer:
Step-by-step explanation:
<u>Given parabola:</u>
<u>Complete the square to convert the equation into vertex form:</u>
- y = x² - 8x + 13 =
- x² - 2*x*4 + 4² - 4² + 13 =
- (x - 4)² - 16 + 13 =
- (x - 4)² - 3
Maximum and minimum value of correlation coefficient are 1 and -1 respectively.
When coefficient (r) = 1, it means that every data set values lies on a straight line or you can say that there is perfect positive linear relationship between two variables. When coefficient(r) = -1, it means that every data set values lies on a straight line but this straight line has negative slope. So they are also said to be perfect negative linearly related.
