So, let’s understand the meaning of a variable first. A variable can be expressed as an entity which can have any value from negative infinity to positive infinity. Suppose there is a variable \(n\) which is a set of natural numbers. So, the value of \(n\) can be a subset of integers \((1, \ 2, \ 3, \ ……….)\). As you can see that \(n\) can take any values ranging from \(1\) to infinity.

Composing functions means combining two or more functions to make a single function. When \(g(x)\) acts first, the combination of functions \(f(x)\) and \(g(x)\) is shown by \(f(g(x))\) or \((f ∘ g)(x)\). When functions are put together, the output of the function inside the parentheses becomes the input of the function outside the parentheses.

In mathematics, a decimal can be defined as a number which has two parts: a whole part and a fractional part, and these two parts are separated by a decimal point. The whole part always represents a number greater than one, while the fractional part, i.e., the part after the decimal, always represents a number less than one.
