Which graph includes a function, its inverse, and a dashed line that verifies the relationship

Option d

Step-by-step explanation:

The graph of an inverse relation is the reflection of the original graph over the identity line, y = x.

So, the graph which contain the line y = x is the correct graph

Graph a ⇒  includes a function, its inverse, and the line x = 1

Graph b ⇒  includes a function, its inverse, and the line y = -x

Graph c ⇒  includes a function, its inverse, and the line y = 1

Graph d ⇒  includes a function, its inverse, and the line y = x

So, the answer is option d

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
