Question

URGENT 20 POINTS
Select each graph that shows a function and its inverse.

Answer 1

A, D

OR

1, 4

Explanation:

On edge it was A and D when I took the Assignment.

Answer 2

Graphically, two functions are inverses when either...

1) You can reflect the graph the graph about y = x.

2) The graph is the same if you switch the x and y axes.

Let's look at the graphs from left to right, call them 1, 2, 3, 4.

#1 is a reflection across that diagonal - so this is an inverse pair.

#2 is a reflection across the y - axis - not an inverse pair.

#3 is a reflection across the x - axis - not an inverse pair.

#4 is a reflection across the line y = -x - not an inverse pair as you change the signs while swapping the axes.

Thus graph #1 (the left most) is the inverse pair.
