Ex 6.2, 2 Show that the function given by f (x) = e2x is strictly increasing on R. Let š„1 and š„2 be real numbers Such that šš < š2 Multiplying both sides by 2 2š„1 < 2š„2 Taking exponential both sides š^2š„1 < š^2š„2 f (šš) < f ( š2) Hence, when x1 < x2 , f(x1) < f(x2) Thus, f(x) is strictly increasing on R.
