Find the Domain e^(x^2)y=xe^y
Problem
Solution
Identify the equation as a relation between
x andy where we seek the domain, which is the set of all possible values for the independent variablex Analyze the functions involved in the equation. The exponential function
eu is defined for all real numbersu Check for restrictions such as denominators that could be zero, square roots of negative numbers, or logarithms of non-positive numbers. None of these are present in the expression
e(x2)*y=x*ey Determine if
y can be expressed as a function ofx for anyx For any real value ofx there exists at least one real value ofy that satisfies the equation (for example, ifx=0 thene0*y=0*ey⇒y=0 .Conclude that since there are no algebraic restrictions on
x in the given relation, the domain consists of all real numbers.
