The true statement about the function f(n) = (n - 1)^2 + 3n is f(-2) = 3

How to determine the true statement?

The function is given as:

f(n) = (n - 1)^2 + 3n

Next, we test the options.

When n = 3, we have:

f(3) = (3 - 1)^2 + 3 * 3

f(3) = 13 -- this is false

f(-2) = (-2 - 1)^2 + 3 * -2

f(-2) = 3 -- this is true

Hence, the true statement is f(-2) = 3
