I made a secant script for the function f = @(x) exp(1)/3*x*exp(-x/3) aslo read as (e/3)*x*e^(-x/3). How do i find the x value corisponding to y= .25. I must make a second script. I graphed the fuction on my computer and it is not a root so how do i go about this issue? I know its 11.08 but how do i write it in code?

fsolve(@(x)f(x)-.25,[0,10]) % two solutions but look into you're area of interest
fplot(@(x)f(x)-.25,[0,11])
