1, I would call a function like a computational machine that take input and process it then gives an output. processing part depends on who you build your machine or how you define your function.

2, a, 4
b, 17
c, 0
3, f(x) = x/4 - 5

In the function you set up, apply a rule, explaining what it should do with the input number, so the output number you get the value what you applied in the rule.

a) 4
b) 17
c) 2 (if its X+2)
0 (if its X×2) /not clear x^2 this sign/

f(x)= x/4-5

This sign ^ means a power relation. For example 2^3= 2 x 2 x 2 (2 to the power of 3) in written language we would put 3 in a smaller size in the upperright corner of 2.

So x^2 basically means multiply by itself.
X times X or (2^2= 2 times 2 = 4)
Or 5^2 = 5 x 5 = 25
