The graph of a function, f(x) , is shown on the grid.

What is the domain of the inverse of f(x)?

• [ -3, ∞)

• [ 3, ∞)

• [ -4, ∞)

• [ 4, ∞)

Which graph is the inverse of the graph shown?

• 
• 
• 
• 

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

• 
• 
• 
• 

Will inverse functions (and their graphs) have the same y-intercept?

• Yes

• No

• Yes, but only if the y-intercept is (0, 0)

Given the function represented by the table, identify the function that is the inverse.

Are these inverse functions?

• yes
• no
• no way to tell
