Math Problem Statement
A function f(x)�(�) includes the points (2, 3)(2, 3), (−5, 1)(−5, 1), and (10, −3)(10, −3) in its graph. Based on this, which of the following points must be included in the graph of f−1(x)�−1(�)?
Choose TWO correct answers.
A.(3, 4)(3, 4)
B.(−3, 10)(−3, 10)
C.(−1, 5)(−1, 5)
D.(−3, −2)(−3, −2)
E.(−5, 1)(−5, 1)
F.(3, 2)(3, 2)
Solution
To solve this problem, we need to understand that if a function contains a point , then its inverse function must include the point . This means the x and y values are swapped in the inverse function.
The points provided for are:
For the inverse function , the corresponding points will be:
- from
- from
- from
Now, let's check which points match these in the options provided:
- B.
- F.
So, the correct answers are:
B and F.

Here are 5 questions to deepen understanding:
- What is the relationship between a function and its inverse?
- How do we identify points in the inverse function graph?
- How would the point in transform in ?
- Can a function have more than one inverse?
- What conditions must a function satisfy to have an inverse?
Tip: Always remember that the graph of a function and its inverse are reflections across the line .
