Your answer is -4 Hope I helped :D
There is a rule for functions:
One input(x-value) can only have one output(y-value).
If one input has more than one output, it is not a function.
(This doesn't apply to outputs, one output can have more than one input and still be a function)
This graph shows a set of ordered pairs that does NOT represent a function because there are two points on x = -3. The input -3 has more than one output of -4 and 4, so it is not a function.
The volume of the cylinder given the radius and the height is 562.2 cubic units
<h3>Volume of cylinder</h3>
- Radius, r = 2 units
- Height, h = 5 units
Volume of a cylinder = πr²h
= 3.14 × 2² × 5
= 3.14 × 4 × 5
= 562.2 cubic units
Therefore, the volume of the cylinder is 562.2 cubic units.
