The document instructs the user to modify a given function code to accept two functions and a number to calculate the derivative of their composition. It provides a sample function code and asks for assistance on how to call the modified function. The goal is to compute and return the derivative value at a specific point.

1. Copy the above function code (the first four code lines) into the Function box and change it so it
takes two functions f and g and one number a and so it finds the derivative of the composition ,
plugs in (read that carefully!) and returns that value. Then submit it.
This was the above function code:
function r = myderivatpoint(f,a)
syms x
r = subs(diff(f(x)),x,a);
end
I also don't know how I'd call the code to function in this. Thanks.
