Understanding functions

True or False: An inverse of a relation is the same as switching numbers around.

• True

• False

What does it mean to find the inverse of a function when given a table of values?

• the x's and y's are switched

• the x's and y's are divided by 2

• the x's and y's are made negative

• the x's and y's are the same

Which graph represents f^-1(x) over the same domain?

• 
• 
• 
• 

Which is the inverse of the table?

• 
• 
• 
• 

Which graph is the inverse of the graph shown?

• 
• 
• 
• 

are these inverse functions?

• no

• yes

• not enough information to tell

Inverses are functions reflected over...

• the line y=x

• the x-axis

• the y-axis

• nothing, they are just rotations

The five points shown are on the graph of y=f(x). Which point would be found in the inverse of this graph (on y=f^-1(x))?

• (0,3)

• (1,0)

• (1,3)

• (-3,-1)
