Given any two functions f and g which of the following state

Given any two functions f and g, which of the following statements is not true? If x is not in the domain of g, then x cannot be in the domain of f o g. If x is in the domain of f and if x is in the domain of g, then x must be in the domain of f o g. The domain of f o g is always a subset of the domain of g. To find the domain of f o g, first find the domain of g, then exclude from the domain of g all values of x for which g(x) is not in the domain of f.

Solution

option B if x is domain of f and x is domain of g then it must be domain of f o g ----- not true
