The domain and range of y equals 2x-8 are both -infinity to +infinity.
The domain is the values that the independent variable, in this case x, can take. The range is the values that the dependent variable, in this case y, will have over the domain. Both x and y can have any value in this case, which is a linear polynomial of degree 1.
domain: (-infinity to infinity) range: ( -infinity to infinity)
The domain would be (...-2,-1,0,1,2...); the range: (12)
domain: all real numbers range: {5}
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].
