Find the Domain 2x-3/5
Problem
Solution
Identify the type of function. The expression
ƒ(x)=(2*x−3)/5 is a linear function, which is a specific type of polynomial.Check for restrictions. In a real-valued function, restrictions on the domain typically occur if there is a denominator containing a variable (which cannot be zero) or an even-indexed root containing a variable (the radicand must be non-negative).
Evaluate the denominator. The denominator is a constant,
5 which is never zero. There are no square roots or logarithms in the expression.Determine the domain. Since there are no values of
x that make the expression undefined, the function is defined for all real numbers.
