Hello!
Acute angles are angles less than 90°
A right angle is a angle that is exactly 90°
A Obtuse angle is a angle that is more than 90°
Looking at the picture there are

Hope this helps!
Answer:
Inverse of f exists.
Step-by-step explanation:
From the graph attached,
If we do the horizontal line test for the function graphed,
We find the function as one to one function.
In other words for every input value (x-value) there is a different output value.
Since, for one-to-one functions, inverse of the functions exist.
Therefore, the answer will be,
The inverse of 'f' exists.
