Here you will learn what is square root function with definition, graph, domain and range. Let’s begin – Square Root Function The function that associates a real number x to +\(\sqrt{x}\) is called square root function. Since \(\sqrt{x}\) is real for x \(ge\) 0. So, we defined the square root function as follows : Definition …
Here you will learn what is reciprocal function with definition, graph and domain and range. Let’s begin – Reciprocal Function The function that associates a real number x to its reciprocal \(1\over x\) is called the reciprocal function. Since \(1\over x\) is not defined for x = 0. So, we define reciprocal function as follows …
