Ex 6.2, 2 Show that the function given by f (x) = e2x is strictly increasing on R. Let ๐ฅ1 and ๐ฅ2 be real numbers Such that ๐๐ < ๐2 Multiplying both sides by 2 2๐ฅ1 < 2๐ฅ2 Taking exponential both sides ๐^2๐ฅ1 < ๐^2๐ฅ2 f (๐๐) < f ( ๐2) Hence, when x1 < x2 , f(x1) < f(x2) Thus, f(x) is strictly increasing on R.
