problem with inputting function handle without using a separate function file

Hi Ive wrote a function called T with inputs f,a,b,n. im not having problems with the a,b,n input values but when i try to input the function handle f the T function prints an error the only way i can stop this is to put the function handle f in a separate function file and us commands like this T(@f,a,b,n) but id like to write T(x,a,b,n) for the function x, how can i do this? thanks
