Answer:
the inverse of f exists
Step-by-step explanation:
From the given graph, the graph is linear
All linear equation represents a line on a graph.
All linear equation is a function. Inverse exists for linear functions.
Inverse exists for the graph of linear function.
Inverse is a reverse of the given function.
For every value of x , there is a y value in graph.
When we remove the x and y values, x values are not repeated.
So, the inverse of f exists
