So what makes a function a function is that each input (x) only has one output (y).
Set A is not a function because when x = 2, y = -2 and 3.
Set B is not a function because when x = 9, y = 3 and -3.
In short, the correct option is "Neither A nor B".
Answer:
The ladder reaches a height of 6 m.
Step-by-step explanation:
Given that,
Height of the ladder, H = 6.5 m
The foot of the ladder is 2.5 m from the foot of the wall.
We need to find the height does the ladder reach. If we consider a triangle in which hypotenuse is 6.5 m, foot of the ladder is 2.5 m then we need to find the height of the ladder i.e.
The ladder reaches a height of 6 m.
Negative numbers aren't in a solution set because in equations and inequalities you have to multiply and divide and a positive number divided by a negative number will be a negative number. Positive divided by positive will be positive. Negative divided by negative will be positive. So that's why negative numbers aren't a solution to any set or equation.
