WebTheorem 11. The graph y = lnx of the function lnx is concave downward. Proof. The second derivative of lnx is 1=x2 which is negative, therefore its graph is concave downward. q.e.d. Theorem 12. The range of the function lnx includes all real numbers. Proof. Let b be any number greater than 1, then c = lnb > 0. Then multiples nc approach … WebMar 18, 2024 · Let R be the region in the first quadrant bounded by the graphs of y= lnx, 1=x ,and 1=y as shown in the figure above.
