The domain can be anything you like as long as it excludes the point x = -40.The range is the set of all values that y can take for the values of x in the domain of your choice.
It depends on the domain but, if the domain is the real numbers, so is the range.
Domain : set of all reals Range: set of all reals
The domain and range of Y = 1.3x + 8 are both [-infinity, +infinity]
The domain and range of the equation y = 2x+8 are both [-infinity,+infinity].
(2x+3) / 5 Domain = All Real Numbers Range = All Real Numbers
The range depends on the domain.
The domain and range are both [-6, +6].
It depends on the domain but, if the domain is the real numbers, so is the range.
Domain : set of all reals Range: set of all reals
The domain and range of Y = 1.3x + 8 are both [-infinity, +infinity]
The range depends on the domain and conversely.
The domain and range of the equation y = 2x+8 are both [-infinity,+infinity].
If the domain is the real numbers then so is the range.
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
(2x+3) / 5 Domain = All Real Numbers Range = All Real Numbers
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.
If the domain is the set of real numbers, so is the range.
