Question

The following points on the graph of a function

X y
2 4
3 5
4 6
5 7
6 8
7 9

Which point would be on the inverse of this function?

A (7,5)
B (-7,-5)
C (-5,-7)
D (-2,-4)

Answer 1

9514 1404 393

Answer:

A (7,5)

Explanation:

The inverse of a function swaps the numbers in each of its ordered pairs.

We notice that all of the function pairs listed have positive numbers, so the inverse function pairs will also be all positive numbers. This eliminates all but the first choice:

(7, 5) is on the inverse function
