No. It depends on how the range is defined.
y = x2 is not onto R but can be made onto by changing the range to R0+.

What does onto mean when referring to functions?
it means you are applying the function onto the number.
What type of function maps an input onto itself?
A function that maps an input onto itself is called an identity function. In other words, the output of the function is the same as the input. The identity function is represented by the equation f(x) = x.
Is the relation a function?
Not every relation is a function. But every function is a relation. Function is just a part of relation.
What is the example of onto function?
y = x
Is every on-to function a one-one function?
No. The function y = x2, where the domain is the real numbers and the codomain is the non-negative reals is onto, but it is not one to one. With the exception of x = 0, it is 2-to-1. Fact, they are completely independent of one another. A function from set X to set Y is onto (or surjective) if everything in Y can be obtained by applying the function by an element of X A function from set X to set Y is one-one (or injective) if no two elements of X are taken to the same element of Y when applied by the function. Notes: 1. A function that is both onto and one-one (injective and surjective) is called bijective. 2. An injective function can be made bijective by changing the set Y to be the image of X under the function. Using this process, any function can be made to be surjective. 3. If the inverse of a surjective function is also a function, then it is bijective.
What is difference between one to one function and onto function?
In simple words, a one-to-one function is a function such that for every input there is a unique output. An onto function is such that ALL the elements in the out are used, something which is not necessary for a one-to-one function. Draw a set A, which contains 3 elements, a, b, c and d. Draw another set B, containing elements e, f, g and h. Make an arrow from "a" to "d", "b" to "d", then "c" to "e" and "d" to "f". Draw the two sets A and B again. This time make an arrow from "a" to "d", "b" to "d", then "c" to "e" and "d" to "e". The fact that "f" in set B has not been used, DOES NOT makes this function an onto function.
What is the main function of a wheel?
To mount the tire onto
Is all relation a function?
Not every relation is a function. A function is type of relation in which every element of its domain maps to only one element in the range. However, every function is a relation.
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 do you find if a relation is a function?
A relationship is a function if every element in the domain is mapped onto only one element in the codomain (range). In graph terms, it means that any line parallel to the vertical axis can meet the graph in at most one point.
Is every function a realation?
Yes, but not the other way round - not every relation is a function.
Function which maps itself onto itself?
f(x) map onto itself means f(x) = x the image is the same as the object
