Answer:
see the explanation
Step-by-step explanation:
Observing the picture
1) For y=-1
The answer is undefined (there is no corresponding value for x)
2) For y=0
we have the points (-3,0) and (6,0)
therefore
x=-3, x=6
3) For y=2
we have the points
(-2.25,2)
(0.75,2)
(4,2)
therefore
x=-2.25, x=0.75, x=4
3) For y=3
we have the points belong to the interval [-2,0]
so
![-2 \leq x \leq 0](https://tex.z-dn.net/?f=-2%20%5Cleq%20x%20%5Cleq%200)
1st question: intersection is the numbers included in both sets
neither set shares any numbers so answer would be null set
2nd question: 2 numbers are in all 3 sets: (-2,9)
To write a number into the scientific notation, we need to move the decimal point of the number to the right if the decimal point is before the value or left up if the point is after the the last number of the value. We need to count how many places we moved the point. Then, we write the value after moving and multiply this by 10 to the power of the number you moved the decimal point. If you moved it to the right, then the power would be a negative value. If moved to the left, then the power is positive. We do as follows:
.10316455696
1.0316455696 x 10^-1 = 1.03 x10^-1
