Answer:
Set the denominator in 4x equal to 0 to find where the expression is undefined. x=0
The domain is all values of x that make the expression defined.
Interval Notation: (−∞,0)∪(0,∞)
Set-Builder Notation: x
The range is the set of all valid y values. Use the graph to find the range.
Interval Notation: (−∞,4)∪(4,∞)
Set-Builder Notation: y
Determine the domain and range.
Domain: (−∞,0)∪(0,∞), x≠0
Range: (−∞,4)∪(4,∞), y≠4
