What is the domain of 3x plus 7?
Any domain that you like. It can be the counting numbers, integers, rationals, reals or complex numbers. Or it can be a subset of any of them. For example, the domain could be {-2, 7, 3.56}.
What is an equation with no solutions?
DIVIDE BY ZERO ERROR Is an equation with no solution's answer. * * * * * It also depends on the domain of the variable(s). For example x + 3 = 2 has no solution if the domain for x is the counting numbers, Z. x*3 = 2 has no solution if the domain for x is the natural numbers, N. x2 = 2 has no solution if the domain for x is the rational numbers, Q. x2 = -2 has no solution if the domain for x is the real numbers, R.
What is the range of y equals 8x-3?

In mathematics how does one find a domain?
In mathematics, the domain of a function is the set of values that provide a real output. For example, for the equations y = 1/x or y - sqrt(x+3), the domain consists of all the values for x that provide a real output for y. For fractions, a denominator of zero will not provide a real output. For even roots, a negative value under the radicand will not provide a real output. One can find the domain by finding these exceptions and excluding them from the domain set.
What is the range of the equation y equals X squared plus 6?
The answer depends on the domain for x. For example, if the domain is x = 7, then the range is 55. If the domain is all Real numbers, then the range is y >= 6.
