Example 26 Find the maximum and the minimum values, if any, of the function f given by f (π₯) = π₯2 , π₯ β R f(π₯)=π₯^2 First we plot the Graph of π^π At x = 0 f(0)=0 And, we note that f(π₯)>0 for all π₯ except 0 Thus, Minimum value of f(π₯)=π at π = 0 Also, Since f(π)>π for all π₯ except 0 So, we cannot find a maximum value Example: f(100)=(100)^2 = 10000 f(1000)= (1000)^2 = 1000000 Hence , we cannot find maximum value of f(π₯) on π β R
