The Range Of The Function F(k) = k2 + 2k + 1 is {25, 64}. What Is The Function’s Domain ?

The range of the function f(k) = k2 + 2k + 1 is {25, 64}. What is the function’s domain?

The domain of a function is the set of all possible inputs to the function. In this case, since there are no restrictions on what k can be, we have an infinite domain. However, in order to have a closed domain, we need to restrict our input in some way.

For example, if we want to restrict our inputs to integers between 1 and 25, then we could use f(x) = x2 + 2x + 1. In this case, our input would be limited to integers between 1 and 26 (i.e., 1 ≤ x ≤ 26).
