Reciprocal Function – Graph, Definition, Domain and Range

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 …

Logarithmic Function – Graph, Definition, Domain and Range

Here you will learn what is logarithmic function graph, formula, domain and range. Let’s begin – Logarithmic Function Definition : If a > 0 and a \(\ne\) 1, then the function defined by f(x) = \(log_a x\), x > 0 is called the logarithmic function. We know that logarithmic function and the exponential function are …
