Describe the domain and range of:

f(x) = — 4/x+1 +3

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|x≠0}

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|y≠4}

Determine the domain and range.

Domain: (−∞,0)∪(0,∞), {x|x≠0}

Range: (−∞,4)∪(4,∞), {y|y≠4}
