Example 26 Find the maximum and the minimum values, if any, of the function f given by f (𝑥) = 𝑥2 , 𝑥 ∈ R f𝑥=𝑥2 First we plot the graph of 𝑥2 Note that at 𝑥 = 0 f0=0 Also we note that f𝑥>0 for all 𝑥 , 𝑥 ∈ R except 0 So minimum value of f𝒙=𝟎 at 𝒙 = 0 Since f𝑥>0 for 𝑥 ∈ R expect 0 So, we can not find a maximum value e.g. f100=1002= 10000 f1000= 10002= 1000000 Hence , we cannot find a maximum value of f𝒙 on , 𝒙 ∈ R
