What is the range of the function f(x)=3/4x-3
kipiarov [429]

Answer:

(-∞,0)∪(0,∞)

Step-by-step explanation:

The domain of a function is wherever the y values exist.  The only time the y values dont exist in this function is when the denominator is zero.  So the denominator does not exist at x=0, because that is when 4x = 0.

-13
