What was the prime region to define this type of function.Is it exists in our nature.If yes Please give an example.??????

if e^x=cx^2 has three real solutions what is the smallest positive integral value of c sir please give the solution

[@gtimeducation]

Equation e^x-cx^2 has three real roots, then the derivative of function f(x) = e^x-cx^2 must have two real roots as between two roots of the equation there exists atleast one root of its derivative. Now f'(x) = e^x - 2cx. Now graph of y = e^x and y = 2cx must intersect at two distinct points. First we find the value of c for which graph touch. For that e^x = 2c (comparing derivatives i.e. slopes). y = 2c and x = 1. So, y = e. i.e. point of contact of line y = 2cx and y = e^x is (1, e), for which 2c = e Thus line y =2cx, touches y = e^x when slope of the line is e. Now if line cuts y = e^x at two distinct points then slope of the line must be more than e, i.e. 2c > e or c > e/2. So, least integral value of c is 2.
