Question
Describe the range of the following absolute value function:๐(๐ฅ)=|๐ฅโ2|+1๐(๐ฅ)=|๐ฅโ2|+1The range is: ๐ฆ
Solution
The range of the function ๐(๐ฅ)=|๐ฅโ2|+1 is ๐ฆโฅ1.
Here's why:
-
The absolute value function |๐ฅโ2| is always greater than or equal to 0 because absolute value represents distance, which can't be negative.
-
When you add 1 to the absolute value function to get |๐ฅโ2|+1, you shift the entire graph up by 1 unit.
-
Therefore, the smallest value the function ๐(๐ฅ)=|๐ฅโ2|+1 can have is 1 (when ๐ฅ=2), and it can increase from there without bound.
So, the range is all real numbers greater than or equal to 1, or ๐ฆโฅ1.
