How to Find Maximum and Minimum Value of a Function

In the function f(x) = 2x^2 + 5x + 4, b = 5 and a = 2. Therefore, you would divide -5 by 2 times 2, or 4, and get -1.25. Finally, plug the x value into the function to find the value of f(x)

Finding Maxima and Minima using Derivatives

f = sin (x)+sin (x*2); f2 = diff (f,x)==0; x = solve (f2,x); X = max (x); However this code gives: acos (- 33^ (1/2)/8 - 1/8) and I want a numerical value because I need to use the
