Answer:
-1 <x < 7
(-1,7)
Step-by-step explanation:
open circle on the left means the number is greater than
-1 <x
Open circle on the right means the number is less than
x < 7
Since both statements are true. we combine them
-1 <x < 7
open circles means parentheses, closed circles mean brackets
We just need to solve for y when x = -2
Solution:
y = 2|-2 + 1|
y = 2|-1|
y = 2(1)
y = 2
Therefore, the answer is Option 3
Best of Luck!
