**How to find the range of a function with absolute value?**<\/p>\n

When dealing with functions that involve absolute value, determining the range can sometimes be a bit challenging. However, with a systematic approach, you can easily find the range of such functions. Let’s explore the steps involved in finding the range of a function with absolute value.<\/p>\n

1. Understand the concept of absolute value:
\n Before diving into finding the range, it is essential to have a clear understanding of absolute value. The absolute value of a number represents its distance from zero on the number line and is always positive or zero.<\/p>\n

2. Determine the expression inside the absolute value:
\n Begin by examining the expression within the absolute value bars. Note that this expression might involve variables or constants.<\/p>\n

3. Set up two cases:
\n Since the absolute value function considers both positive and negative values, we need to investigate both possibilities. Establish two cases: one where the expression inside the absolute value is positive and another where it is negative.<\/p>\n

4. Solve for positive values:
\n In the first case, assume that the expression inside the absolute value is positive. Solve the equation formed by equating the expression to the positive value without the absolute value. Find the values of variables that satisfy this equation.<\/p>\n

5. Solve for negative values:
\n In the second case, assume that the expression inside the absolute value is negative. Solve the equation formed by equating the expression to the negative value without the absolute value. Again, find the values of variables that satisfy this equation.<\/p>\n

6. Combine the solutions:
\n Merge the solutions obtained from both cases to determine the complete range of the absolute value function. Depending on the nature of the function, specify the range in different ways, such as intervals or inequalities.<\/p>\n

7. Consider any restrictions:
\n If there are any restrictions or limitations mentioned in the problem or question, make sure to apply them while determining the final range. This could include restrictions on variables or certain conditions that affect the range.<\/p>\n

8. Check for extraneous solutions:
\n After obtaining the range, double-check for any extraneous solutions. Sometimes, during the manipulation of equations or inequalities, additional solutions may arise that do not actually satisfy the original absolute value function.<\/p>\n
