Ex 6.2, 4 Find the intervals in which the function f given by f (đĽ) = 2đĽ2 â 3đĽ is (a) strictly increasing (b) strictly decreasing f (đĽ) = 2đĽ2 â3đĽ Calculating fâ(đ) đ^â˛ (đĽ) = 4đĽ â 3 Putting fâ (đ) = 0 4đĽ â 3 = 0 4đĽ = 3 đĽ = 3/4 Plotting point on number line Hence, f is strictly increasing in (đ/đ , â) f is strictly decreasing in (ââ ,đ/đ)
