find the domain and the range of the following rational functions
1.y=2x-1/x+4
2.y=x/x²-4
3.y=x²+x/x²-2x-3
4.y=2x-3/3x+6
5.y=-3/x+2
need ko po please
1.y=2x-1/x+4
2.y=x/x²-4

Answer:
Andami naman
Step-by-step explanation:
1.y=2x-1/x+4
x+4=0
x≠-4
Domain={x|x€R , if x is not equal to -4}
Range
y=2x-1/x+4
y(x+4)=2x-1
xy+4y=2x-1
xy-2x=-4y-1
x(y-2)/y-2 = 4y-1/y-2
x=4y-1/y-2
y-2≠0
y≠2
Range={y|y € R , y is not equal to 2}
