The mapping diagram shows a function q(x).
> 1
> 2
> 3
> 4
which mapping diagram shows the inverse of q(x)?

B.   1>2

                     2>4

                     3>6

                     4>8

Step-by-step explanation: We are given mapping diagram of function Q(x).

2>1

4>2

6>3

8>4

We need to find the mapping diagram of inverse of Q(x).

Note: The inverse function switches the x and y mapping to y and x mapping.

(x,y) would become (y,x) or (a,b) would become (b,a).

So, each mapping would just flip and we get

                     1>2

                     2>4

                     3>6

                     4>8

Which is the mapping in option B.

what are ur choices?
