Hi there, I have a function f(x) and need to determine where f(x) is increasing and decreasing
So I determined the derivitive of f(x) as Df.
I need to get the values of x where y=0 of Df to 4 decimal places.
I am asking if someone could help me.
- To get the points where Df(x) = 0
- To get these values rounded to 4 decimal spaces
This is the graph of Df
Code i used to get here:
syms f(x)f(x) = x.*(cos(x.^2)) - exp(sqrt(x)) + x.^3 - 4*(x.^2);Df = diff(f,x);fplot(Df, [0 4], 'b')grid onxlim([0.00 4.00])ylim([0.0 27.3])
