Math Problem Statement
A function f(x) includes the points (2, 3) , (−5, 1) , and (10, −3) in its graph. Based on this, which of the following points must be included in the graph of f−1(x) ?
Choose TWO correct answers. A.(3, 4)
B.(−3, 10)
C.(−1, 5)
D.(−3, −2)
E.(−5, 1)
F.(3, 2)
Solution
For a function and its inverse , the points on the graph of and are related in a very specific way. If , then . Essentially, the - and -coordinates of each point on the graph of are swapped for the corresponding point on the graph of .
Given that includes the points , , and , their corresponding points on will be:
- on becomes on .
- on becomes on .
- on becomes on .
Thus, the correct points that must be included in the graph of are:
- B. (-3, 10)
- F. (3, 2)
