How to use the feval() function to evaluate the two input argument functions?

I need help with this homweork problem using feval(). I have tried using 'feval(xVal,denomFun(xVal))' but it keeps saying I am wrong. Thanks in advance.

The first argument to feval() needs to be the function to evaluate. You are trying to pass a value instead.

General syntax:

feval(Function_Information, parameter1, parameter2, ...)

For feval, the Function_Information can be a function handle, or an inline object, or a symbolic function (not a symbolic expression), or a scalar string object, or a character row vector (or some curvefit objects.)
