1. 1. The restriction on the value under the square root symbol is that all of them must be greater or equal to 0. The domain of this function are all real numbers (2, 3, 4, ….., ∞).

   What is a function?

   A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables.

   The types of function.

   In Mathematics, there are different types of functions and these include the following;

   • Periodic function

   • Inverse function

   • Modulus function

   • Signum function

   • Piece-wise defined function.

   For the given function f(x) = 3√(x – 2), the restriction on the value under the square root symbol is that it cannot take a negative number. This ultimately implies that, all the values under the square root symbol must be greater or equal to 0.

   What is a domain?

   A domain can be defined as the set of all real numbers for which a particular function is defined. Thus, the domain of this function are all real numbers and these include the following:

   • 2

   • 3

   • 4

   • 5

   • ∞
