A mapping, f, from set S to set T is said to be surjective if for every element in set T, there is some element in S such that it maps on to the element in T.
Thus, if t is any element of T, there must be some element, s, in S such that f(s) = t.

What is mapping in algebra?
A mapping is a relationship between two sets. Given sets A and B (which need not be different) a mapping allocates an element of B to each element of A.
Prove or disprove if the composition fg is surjective than f and g are surjective?
counter example: f(x)= arctan(x) , f:R ->(-pi/2 , pi/2) g(x)=tan(x) , g:(-pi/2, pi/2) -> R (g(x) isn't surjective) f(g(x))=arctan(tan(x))=x f(g(x)): R -> R Although, if two of the three are surjective, the third is surjective as well.
What is a algebra mapping?
A mapping consists of two sets and a rule for assigning to each element in the first set one or more elements in the second set. We say that A is mapped to B and write this as m: A→B.
What is the domain of algebra?
Among other topics, algebra deals with mappings. These are relations between two sets - which can be the same. A mapping is a process which assigns an element in the second set to each element of the first set. The first set is the domain and the second is the range.For example, if the mapping is "square the number" and the domain is {-3, 1, 2, 3}, then the range would be {9, 1, 4, 9} which is the same as {1, 4, 9}.
What are some function words?
Domain, codomain, range, surjective, bijective, invertible, monotonic, continuous, differentiable.
What is an input or output relation that has exactly one output for each input?
A one-to-one function, a.k.a. an injective function.

How is algebra used in architecture?
Algebra is widely utilized in architecture. Architects use algebra to solve structural problems and issues. They also use it for planning, mapping, developing and implementation.

What is direct mapping and mapping function?
it means mapping directly

What does a function need to have for it to be a function algebra?
A function is a mapping from a set, called the domain, to a set (which may be the same) called a co-domain or range such that for each element in the domain, there is at most one element in the co-domain. Another way of stating the last bit is that the mapping can be one-to-one or many-to-one but not one-to-many.
What genetic mapping is?
genetic mapping is the mapping of genes to locations within a genome.
