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.

A relation in which each element of the domain is paired with exactly one element of the range?
A relation where each element of the domain is paired with only one element of the range is a one to one function. A one to one function may also be an onto function if all elements of the range are paired.
Can an invertible function have more than one x-intercept?
No. If the function has more than one x-intercept then there are more than one values of x for which y = 0. This means that, for the inverse function, y = 0 should be mapped onto more than one x values. That is, the inverse function would be many-to-one. But a function cannot be many-to-one. So the "inverse" is not a function. And tat means the original function is not invertible.
What is a common difference in algebra?
Common difference, in the context of arithmetic sequences is the difference between one element of the sequence and the element before it.
What distinguishes a linear function from other functions?
A linear function is one in which the power of the function is only one. So, the graph of it would be a straight line. For example, x2 + x = y is not linear, because the highest power is 2. A main difference is, non linear functions have curves, where as a linear function is a straight line, with the exception of when the function has a power of 0, and it is technically a straight line.
What is the difference between algebra one and algebra two?
A harder version of algebra 1
What is the difference between function and use?
what is the difference between function and use? I came across with this problem while I am doing my bilogy home work for instace what is the use of glucose ?and second one is what is the function of glucose? so is for protein

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.
What is the difference between rational and polynomials?
A polynomial function is simply a function that is made of one or more mononomials. For example 4x^2+3x-5 A rational function is when a polynomial function is divided by another polynomial 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 one and one's?
difference between one- ones
A relation in which each element of the domain is paired with exactly one element of the range?
A relation where each element of the domain is paired with only one element of the range is a one to one function. A one to one function may also be an onto function if all elements of the range are paired.
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.
Y equals 4x plus 3 is this a one to one function or an onto function and does it have an inverse function?
Assuming the domain and range are both the real numbers (or rationals): Yes, it is 1 to 1 Yes, it is onto and the inverse is x = (y-3)/4
What is the difference between function and objective?
Function can be mentioned as an action performed by a device, department or person that produces a result. It remains more or less fixed. On the other hand,objective may be referred to as something that one's effort or actions are intended to attain or accomplish. Thus, there is a very thin line of difference between these two terms.
What is the difference between function and form?
u just suck it up princess and get the answer yourself because no one is gonna help on ur assignment
How do you identify a function?
A function is a mapping from one set to another such that each element from the first set is mapped onto exactly one element from the second set.
