Use quadratic regression to find the equation of a quadratic function that fits the given points. x 0 1 2 3

y 29 42 62 38

y = 26.45 + 32.45x - 9.25x

Step-by-step explanation:

Given the data:

X : 0 1 2 3

Y : 29 42 62 38

The quadratic regression model has the general equation :

y=A+Bx+Cx2

Fitting the data using a quadratic regression calculator, the equation of best fit obtained is ;

y = 26.45 + 32.45x - 9.25x

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
