HELP LIKE RN. I really need help tbh.

Answer:
f(x) = 3x - 16
Step-by-step explanation:
y = 3x - 16 is a function in which y is a function of x.
To write it in function notation, we replace y with f(x). f(x) means that the function named f is a function of x. All you need to do is replace y with f(x).
f(x) = 3x - 16
