Ex 6.2, 6 Find the intervals in which the following functions are strictly increasing or decreasing: (d) 6 â 9đĽ â đĽ2 đ(đĽ) = 6 â 9đĽ â đĽ2 Calculating fâ(đ) fâ(đĽ) = â9 â 2đĽ fâ(đĽ) = â(2đĽ+9) Putting fâ(đ) = 0 â(2đĽ+9) = 0 2đĽ + 9 = 0 2đĽ = â 9 đ = (âđ)/đ Plotting point đ = (âđ)/đ on real line Hence f is strictly Increasing for đ < (âđ)/đ & strictly Decreasing for đ > (âđ)/đ
