Example 10 Find the intervals in which the function f given by f (x) = x2 ā€“ 4x + 6 is (a) strictly increasing (b) strictly decreasingf (š‘„) = š‘„2 ā€“ 4š‘„ + 6 Calculate fā€™(š’™) š‘“ā€™ (š‘„) = 2š‘„ ā€“ 4 Calculate fā€™(š’™) = 0 2š‘„ ā€“ 4 = 0 2š‘„ = 4 š‘„ = 4/2=2 Hence š‘„ = 2 divide real line into 2 disjoint intervals. Plotting points on number line
