The domain and range of the equation y = 2x+8 are both [-infinity,+infinity].
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.
The domain is related to the range depending on the equation or equations given. Without this context, the domain for a Cartegian plane (2 dimensions) is simply R, or all real numbers. With a linear equation (absolute value/ dependent variation) a more useful and specific answer can be given.
If the domain is the set of real numbers, so is the range.
Domain is the spectrum of values on the x-axis. Domain will be which x-values can be plugged into that equation and give an answer. Range is the same thing, but y-values. On the graph it will be the y-values that are included in the graph.
Domain is the independent variable in an equation. It is what you put "in" the equation to get the Range.
5
The domain and range are both [-6, +6].
You need to know the domain first. For each value in the domain there will be a value for the function (or expression). These may not all be different. The set of these values is the range of the equation.

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.
Find all possible "x" and "y" values for domain and range. Then put it in inequality form. For example the domain and range for the equation 2x-3/x-5 would be: Domain: All Reals; x>5 Range: All Reals
Any equation which maps each value of x in the domain to a value in the range is a function of x.
