No.
For example, y = 7 is monotonic. It may be a degenerate case, but that does not disallow it. It is not a bijection unless the domain and range are sets with cardinality 1.
Even a function that is strictly monotonic need not be a bijection. For example, y = sqrt(x) is strictly monotonic [increasing] for all non-negative x. But it is not a bijection from the set of real numbers to the set of real numbers because it is not defined for negative x.

Is every bijection a strictly monotonic function?
No. For example, consider the discontinuous bijection that increases linearly from [0,0] to [1,1], decreases linearly from (1,2) to (2,1), increases linearly from [2,2] to [3,3], decreases linearly from (3,4) to (4,3), etc.
What is a bijection?
A bijection is a one-to-one correspondence in set theory - a function which is both a surjection and an injection.
When does a relation be a function?
A function is a relation whose mapping is a bijection.
What is the difference between relations and functions?
A function is a relation whose mapping is a bijection.
Is a strictly monotonic function absolutely continuous?
No, they can only be jump continuous.
Is every bijection a strictly monotonic function?
No. For example, consider the discontinuous bijection that increases linearly from [0,0] to [1,1], decreases linearly from (1,2) to (2,1), increases linearly from [2,2] to [3,3], decreases linearly from (3,4) to (4,3), etc.
Does the greatest integer function have an inverse function?
Inverse of a function exists only if it is a Bijection. Bijection=Injection(one to one)+surjection (onto) function.

How does a monotonic transformation affect the shape of a function's graph?
A monotonic transformation does not change the overall shape of a function's graph, but it can stretch or compress the graph horizontally or vertically.
What is a monotonic transformation and how does it impact the relationship between variables in a mathematical function?
A monotonic transformation is a mathematical function that preserves the order of values in a dataset. It does not change the relationship between variables in a mathematical function, but it can change the scale or shape of the function.
What is the correspondence of the domain and range of a linear function?
It is a bijection [one-to-one and onto].
What is the difference between relations and functions?
A function is a relation whose mapping is a bijection.
What is a type of function whose graph is a nonvertical line?
A monotonic, or one-to-one function.
How do monotonic transformations affect the relationship between variables in a mathematical function?
Monotonic transformations do not change the relationship between variables in a mathematical function. They only change the scale or shape of the function without altering the overall pattern of the relationship.
Is a strictly monotonic function absolutely continuous?
No, they can only be jump continuous.
