Question

Use technology to construct an appropriate model of the data,

(0.1). (1, 2), (2, 3), (3,-2), (4.1)

Answer 1

Quadratic model

Explanation:

Given the data :

(0.1). (1, - 2), (2, - 3), (3,-2), (4.1)

The above data point when plotted using technology gives a quadratic model with the equation : x² - 4x + 1

With the quadratic regression model for the data above, we obtain a correlation Coefficient of 1 ; which means a perfect relationship exists between the x and y variables.
