The requiredcubic modelwould be y = 1 + x³ for the givensetofvalues.What is the cubic model?Thecubic modelfunction takes the form:y = a + bx + cx² + dx³,where a, b, c, and d are realintegersthat represent the cubic regression model'scoefficientsAs you can see, we simulate how thevalueof y changes as x changes.x₁ = -2, y₁ = -7x₂ = -1, y₂ = 0x₃ = 0, y₃ = 1x₄ = 1, y₄ = 2x₅ = 2, y₅ = 9Computing the values in theregression modelsto get the values ofcoefficientsto which thegraphhas attached.y = a + bx + cx² + dx³Fittedcoefficients:a = 1b = 0c = 0d = 1Cubic model:y = 1 + x³Hence, the requiredcubic modelwould be y = 1 + x³ for the givensetofvalues.To learn more about thecubic modelhere :brainly.com/question/2531100#SPJ1...
