Look at fcnstr. Notice that it only has x's as variables, so when you create the inline function, there is only one variable, so only 1 argument.
Somewhere after you make the function f, type "keyboard" and run your code. You will be stopped at this line. Then, in your command window, type "f", and you'll see what it looks like:
f =
Inline function:
f(x) = x^2 - 3*x^3 + 0.5*x^4
