Not sure why I am getting errors for my anonymous functions.

I have this code:

k = randn(1); % random variable
% define all of your variables below
f = @(x) (sin(x)+4.*x)/x.^2
A = f(5)
g = @(x,k) exp(cos(x)).^k
B = g(pi/4,k)
x = [0:0.1:1]
C = g(f(g(x)))

and when I run it I get these two errors:

Not enough input arguments.

Error in solution>@(x,k)exp(cos(x)).^k (line 5)

g = @(x,k) exp(cos(x)).^k

Error in solution (line 8)

C = g(f(g(x)))

That's one error.

g takes two inputs, but you are giving it only one when you use it here:

C = g(f(g(x)))

The input given to g is x. What k is it supposed to use?

This would work:

k = randn(1); % random variable
% define all of your variables below
f = @(x) (sin(x)+4*x)./x.^2;
A = f(5);
g = @(x,k) exp(cos(x)).^k;
B = g(pi/4,k);
x = [0:0.1:1];
C = g(f(g(x,k)),k)

C = 1×11
