A function is a relationship between inputs where each input is related to exactly one output.
n = 2 is the input
f(2) = -2 is the output
The value of f(n) at n = 2 is -2.
<h3>What is a function?</h3>
A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(n) = n² - 3n
when n = 2 we get,
f(2) = 2² - 3 x 2 = 4 - 6 = -2
Thus,
n = 2 is the input
f(2) = -2 is the output
The value of f(n) at n = 2 is -2.
