Question

1. Find the domain of the function
f(x)= 3x/28-x

​

Answer 1

Step-by-step explanation:

Domain is all x for which f(x) is defined .

So except x= 28 , all real values .

x belongs to R but x≠28

Answer 2

Step-by-step explanation:

$Given \: it \: \\ f(x) = \frac{3x}{28 - x} \\ for \: f(x) \: is \: defined \: \\ \: \: \: \: \: \: 28 - x \: is \: not \: equal \: to \: zero. \\ \\ Hence \: f(x) \: is \: defined \: for \: all \: real \: values \: except \: 28. \\ \\ Hope \: it \: will \: help \: you.$
