Answer:

Step-by-step explanation:
Hello,

as

I do not understand why there are two decimal places.
But either ways if you are asking for :
0.0000489 then it is 4.89*10⁻⁵
0.489 then it is 4.89*10⁻¹
The trick is to count the zeroes to the first actual significant number you see and then write the number you counted with a negative sign for your power.
I hope this helps!
The number is 6 because 14+6=20 and 6 is less than 14. Hope this helps.
The domain is x such that x belong to real number
Horizontal- y=-1/2
vertical- x=5
x intercepts- (-2,0)
y intercepts- none
hole- (0, 1/5)
