Given the the table of values below which of the following ordered pairs are found on the graph of the inverse function?
Alja [10]

Answer:

C

Step-by-step explanation:

From the table we see that

f(-2)=12\\ \\f(-1)=10\\ \\f(0)=8\\ \\f(1)=6\\ \\f(2)=4

Thus, the inverse function has the rule

f^{-1}(12)=-2\\ \\f^{-1}(10)=-1\\ \\f^{-1}(8)=0\\ \\f^{-1}(6)=1\\ \\f^{-1}(4)=2

This gives us that ordered pairs

(12,-2),\ (10,-1),\ (8,0),\ (6,1),\ (4,2)

are on the graph of the inverse function
