When you compare two functions f(x) and g(x), you're looking for a special input
such that

Since you have the table with some possible candidates for
, you simply have to choose the row that gives values for f(x) and g(x) that are as close as possible (the exact solution would give the same value for f(x) and g(x), so the approximate solution will give values for f(x) and g(x) that are close to each other).
In your table, the values for f(x) and g(x) are closer when x=-0.75
it is a rational number (intergers are plus and minus whole numbers)
The volume of a Cylinder is:

the base is a circle, so

replacing

now we have the values

Answer: Height is 5 units.
Step-by-step explanation:
Alright, lets get started.
The area of the triangle is 
The area is given as 30
The base is given as 12
Plugging the values in formula


Dividing 6 in both sides



Hence the height of the triangle is 5 units.........Answer
