Find the Domain z=8x+5y
Problem
Solution
Identify the type of function provided. The expression
z=8*x+5*y is a linear function of two variables,x andy Check for restrictions such as denominators that could be zero, square roots of negative numbers, or logarithms of non-positive numbers.
Determine that there are no such restrictions in this polynomial expression, meaning the variables
x andy can take any real value.Express the domain as the set of all ordered pairs
(x,y) in the two-dimensional real plane.
