Question

In a sequence described by a function, what does the notation f(3) = 1 mean?

Answer 1

In this case f(3) = 1 means the value of  a  member of the sequence when x = 3 is 1.

For example  if the sequence is the values of x^2 - 8   from 1 to infinity, then

f(1) would have a value 1^2 -8 = -7 and f(3)  would be (3)^2 - 8 = 1

Answer 2

Step-by-step explanation:

Function notation is the way a function is written. It is meant to be a precise way of giving information about the function without a rather lengthy written explanation. ... The f (x) notation is another way of representing the y-value in a function, y = f (x).
