Math Problem Statement
Solution
The given function from the image is:
This is a rational function, meaning it is a ratio of two polynomials. Let's simplify it if possible and discuss its properties, such as domain restrictions.
Step 1: Factorize the numerator and denominator
-
Numerator:
- This factors as .
-
Denominator:
- This is a difference of squares, which factors as .
So, the function becomes:
Step 2: Cancel common factors
The term appears in both the numerator and the denominator, so we can cancel it out, provided (because division by zero is undefined).
This simplifies to:
Step 3: Domain restrictions
We have two values where the denominator of the original function becomes zero:
Thus, the domain of the function is all real numbers except and .
Final simplified form:
Would you like to explore this function further, such as finding vertical and horizontal asymptotes or graphing the function? Let me know if you have any questions!
Here are 5 relative questions based on the function simplification:
- What are the vertical asymptotes of the simplified function?
- What is the horizontal asymptote of this rational function?
- How would you find the x-intercept and y-intercept of this function?
- Can you explain why is a removable discontinuity?
- How would you describe the behavior of this function as ?
Tip: Always remember to check for domain restrictions before simplifying any rational expression to avoid undefined values.
