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.
The domain and range of Y = 1.3x + 8 are both [-infinity, +infinity]
Domain : set of all reals Range: set of all reals
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.
It depends on the domain but, if the domain is the real numbers, so is the range.
The domain and range are both [-6, +6].
The domain and range of Y = 1.3x + 8 are both [-infinity, +infinity]
Domain : set of all reals Range: set of all reals
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.
