Question
Find the maximum value of 
.
- -4
- -2
- 0
- 2
Hint:
A function in maths is a special relationship among the inputs (i.e. the domain) and their outputs (known as the codomain) where each input has exactly one output and the output can be traced back to its input.
The correct answer is: 2
So, the maximum value of g(x) is 2.
The minimum and maximum of a function are also called extreme points or extreme values of the function.
