Which best describes the function notation f(3)=15
horsena [70]
If you are given a function, say f(x) = mx+c
This function would give you the relation between two variables, in other words it tells you the output when an input "x" is inserted.

The input for your function would be "x" and the output would be the result of the equation given.

Based on this:
for f(3) = 15, the input (x) would be 3 and the output would be 15

Therefore, the correct choice is:
<span>B) the output is 15, the input is 3</span>
