Have a read here and here. It will greatly improve your chances of getting an answer.
You can find guidelines for posting homework on this forum here. If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks). If your main issue is with understanding the underlying concept, you may consider re-reading the material you teacher provided and ask them for further clarification.

Hi Alma,
As per my understanding, you want to solve the non-linear equation "f(x)" in the range "[0,1]".
To solve a system of non-linear equations, the function "fsolve" can be used. Please look at the following code, for your reference:
x=0:1;
f=@(x) cos(x)-sqrt(x);
s=fsolve(f,x);
where, "f" is the non-linear equation, "x" is the range and "s" is the required solution.
You can refer to the documention of "fsolve" here:
Solve system of nonlinear equations - MATLAB fsolve - MathWorks India
Hope this answer helps you.
Thanks,
Bhanu Prakash.
