Ex 6.3, 4 Prove that the following functions do not have maxima or minima: (iii) ℎ(𝑥)= 𝑥^3+𝑥^2+𝑥+1Here 𝑎 = 3, b = 2, & c = 1 x = (− 2 ± √(4 − 4(3)(1)))/6 x = (− 2 ± √(4 − 12))/6 x = (−2 ± √(− 8))/6 x = (− 2 ± 2√(− 2))/6 x = (−𝟏 ± √(− 𝟐))/𝟑 Since root has minus sign, x has no real value ∴ h (x) does not have a maxima of minima
