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 f(x)f(x) contains a point (a,b)(a, b), then its inverse function f1(x)f^{-1}(x) must include the point (b,a)(b, a). This means the x and y values are swapped in the inverse function.

The points provided for f(x)f(x) are:

  • (2,3)(2, 3)
  • (5,1)(-5, 1)
  • (10,3)(10, -3)

For the inverse function f1(x)f^{-1}(x), the corresponding points will be:

  • (3,2)(3, 2) from (2,3)(2, 3)
  • (1,5)(1, -5) from (5,1)(-5, 1)
  • (3,10)(-3, 10) from (10,3)(10, -3)

Now, let's check which points match these in the options provided:

  • B. (3,10)(-3, 10)
  • F. (3,2)(3, 2)

So, the correct answers are:

B and F.

Would you like further clarification or details?

Here are 5 questions to deepen understanding:

  1. What is the relationship between a function and its inverse?
  2. How do we identify points in the inverse function graph?
  3. How would the point (7,4)(7, 4) in f(x)f(x) transform in f1(x)f^{-1}(x)?
  4. Can a function have more than one inverse?
  5. 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 y=xy = x.
