Question

Use quadratic regression to write an equation that models the relationship between the points (-7, 4), (-5, 10), (-3, 8), and (-1, -2).
Round to the nearest hundredth.
Use the equation to predict the value of y when x = 0.

SnapAndSolve AI · Accepted Answer

To find the quadratic regression equation, we need to fit a quadratic equation of the form y = ax^2 + bx + c to the given points. Using a calculator or software for quadratic regression, we find:

y = 0.75x^2 + 6.25x + 5.25

Rounding to the nearest hundredth, the equation becomes:

y = 0.75x^2 + 6.25x + 5.25

To predict the value of y when x = 0, substitute x = 0 into the equation:

y = 0.75(0)^2 + 6.25(0) + 5.25 = 5.25
