Answer:
You need to satisfy the equation.
I will solve one.
Step-by-step explanation:
x -2 < -5
now add + 2 to both sides to keep its value.
now we end up with x <-3, which means that the value of x should be less than -3 in order to satisfy the equation.
So -5 is an answer, -4 is an answer, but not -3 because it should be less than -3 not equal.
As for number 9 the dash underneath the less than symbol means that it can equal to.
Hope this helps.
Answer:
This relation is NOT a function. In order for an equation to represent a function, every x in the range of the function must only have one y -value.
