Answer:
1) f is the name of the function
2) x is the argument
3) output is (3x + 1)
Explanation:
In function notation, The expression "f (x)" simply means that f is a formula that has an input variable known as "x". It should be noted that f(x) does not imply that we multiply f and x. Hence, f is the name of the function.
Now, the term "x" is an input variable known as the argument of the function.
f(x) is the output of the function and is; 3x + 1
