The function f(x)=x^2 -2x -24x^(1/2) has one stationary point. Find the value of x when f(x) is stationary, and hence determine the nature of this stationary point.

dy/dx = 2x - 2 -12x -1/2 dy/dx = 02x - 2 - 12x -1/2 = 0x = 4 (stationary point)d 2 y/dx 2 = 2 + 6x -3/2 when x=4, d 2 y/dx 2 = 11/411/4 > 0 therefore the point is a minimum
