Thank you Matgas! If x is 2… and
2(4) - 5
8 - 5
5 - 2(4)
5 - 8
those answers would be different…
Sure, you get different answers if you put the (-5) before or after the division. What I meant was that the perfect answer probably is:
5 - x/4 = f(x)
x/4 - 5 =f(x)
and it does not matter which one you use as the description allows both interpretations. Sry for being not accurate enough in the first post

Thank you!! Phew! I was very close. I was just a little confused seeing so many with - 5 at the end! Thank you Matgas! Very helpful.

I disagree with all of you.
0 ^ 2 = 2.
What is your reference for the meaning of ^? (the caret)

entering the equation is this:
f (x) = {
x ^ 2 if x is even
x + 10 if x is odd
}
0 is not even or odd. It’s condition for function.
1.a function is giving the same mathematical formula for each entered unit
2.a=4
b=17
c=0
3. f(x)=x/4-5
