Ex 6.2, 4 Find the intervals in which the function f given by f (๐ฅ) = 2๐ฅ2 โ 3๐ฅ is (a) strictly increasing (b) strictly decreasing f (๐ฅ) = 2๐ฅ2 โ3๐ฅ Calculating fโ(๐) ๐^โฒ (๐ฅ) = 4๐ฅ โ 3 Putting fโ (๐) = 0 4๐ฅ โ 3 = 0 4๐ฅ = 3 ๐ฅ = 3/4 Plotting point on number line Hence, f is strictly increasing in (๐/๐ , โ) f is strictly decreasing in (โโ ,๐/๐)
