I didn't even do math functions back in school and I can still figure it out.
I'll get you started:
65+f(1/4)=65*f(1/4)
64*f(1/4)=65
f(1/4)=65/64
f(1/4)=1.015625
You can figure it out from here surely. Think about what mathematical equation would get 65 from 4 and 1.015625 from 1/4 and then apply it to the number 6. It's stupidly obvious when you think about it. Post back here with the function when you are done and I will tell you if it is correct.

Nobody is going to do your homework for you.
