The absolute value function is an even function.
In the realm of mathematics, functions are often categorized based on their properties and characteristics. One such property is “evenness,” which plays a significant role in understanding how to get the absolute value on a TI-84 Plus calculator. An even function is one that satisfies a specific condition: when the input value is replaced by its negative, the output value remains the same. This concept is closely tied to the concept of absolute value and has practical implications when working with the TI-84 Plus calculator.
To delve deeper into this connection, let’s consider the absolute value function. The absolute value of a number, often denoted as |x|, is its distance from zero on the number line, disregarding its sign. This means that the absolute value of both positive and negative numbers is always positive. This inherent property makes the absolute value function an even function.
For example, if we input -5 into the absolute value function on a TI-84 Plus calculator, the output will be 5. Similarly, if we input 5, the output will also be 5. This observation aligns with the definition of an even function, where the output remains unchanged when the input is replaced by its negative.
Understanding the absolute value function as an even function is crucial for several reasons. First, it helps us comprehend the behavior of the function and predict its output for different inputs. Second, it enables us to simplify certain mathematical expressions and equations involving absolute values. Third, it forms the foundation for further exploration of the absolute value function and its applications in various mathematical contexts.

This property makes it a valuable tool for solving equations involving absolute values, and the TI-84 Plus calculator provides a convenient platform to evaluate these equations.
- Isolating the Absolute Value Expression
One common technique is to isolate the absolute value expression on one side of the equation and simplify the other side. For example, consider the equation |x – 2| = 5. To solve for x, we isolate the absolute value expression by subtracting 2 from both sides, resulting in |x – 2| – 2 = 3. This simplifies the equation to x – 2 = 3 or x – 2 = -3, which can be easily solved to find the values of x that satisfy the equation.
- Splitting into Cases
Another approach is to split the equation into cases based on the possible signs of the expression inside the absolute value. For instance, if we have the equation |2x + 1| = 3, we consider two cases: one where 2x + 1 is positive and the other where it’s negative. This leads to the system of equations 2x + 1 = 3 and 2x + 1 = -3, which can be solved separately to find the solutions for x.
