Answer:
Domain = (-∞,∞)
Range = (-∞,∞)
This is a linear function.
So, if you were to graph this you'd know that it crosses the x and y axis and continues on forever without stopping.
in that case the domain and range are considered infinite on both axes.

Answer: (x,y)=(14/4,0)
Step-by-step explanation:
y=-2(x-3)(2)+2
Clear the brackets
y=-2(2x-6)+2
y=-4x+12+2
y=-4x+14
To get the x-intercept y=0
0=-4x+14
4x=14
x=14/4
(x,y)=(14/4,0)
