Ex 6.2, 6 Find the intervals in which the following functions are strictly increasing or decreasing: (a) đĽ2 + 2đĽ â 5 f(đĽ) = đĽ2 + 2đĽ â 5 Calculating fâ (đ) fâ(đĽ) = 2đĽ + 2 fâ(đĽ) = 2 (đĽ + 1) Putting fâ (đ) = 0 2 (đĽ + 1) = 0 (đĽ + 1) = 0 đ = â1 Plotting point on real line Hence, f is strictly decreasing for (ââ ," â1" ) f is strictly increasing for ( "â1" ,â)
