Is sequence a function?
yes it is a function because sequence defined as "a function whose domain is set of natural number"
A sequence is a whose domain is the set of natural numbers?
true
Why the graph of a sequence cannot be a line or a curve?
A sequence can be thought of a list of numbers written in a definite order:a1, a2, a3, ..., a(n+1), an, ...The number a1 is called the first term, a2 is the second term, and in general an is the nth term.For every positive integer n, there is a corresponding number an, and so a sequence can be defined as a function whose domain is the set of all positive integers. But, we usually write an instead of the function f(n) for the value of the function at the number n.Notation: The sequence {a1, a2, a3, ...} is also denoted by {an}.Some sequences can be defined by giving a formula for the nth term. For example:an = (n)/(n +1) the sequence is {1/2, 2/3, 3/4, 4/5, ..., (n)/(n+1), ...}this sequence can be pictured either by plotting its terms on a number line, or by plotting its graph. Since a sequence is a function whose domain is the set of positive integers, its graph consists of isolated points with coordinates (1, a1), (2, a2), (3, a3), ..., (n, an).Try to plot the graph of this sequence, and you will see that the terms of the sequence an = n/(n+1) are approaching 1 as n becomes large. In this case 1 is the limit for this sequence, and we can write:lim n -->∞ an = 1
Could this ever be the rule of a function For input x the output is the number whose square is x If so what is its domain and range?
Yes, the domain(input) would be all natural numbers (numbers greater or equal to zero). The range (output) would be all real numbers. -- Not only natural numbers would be considered part of this domain, all negative numbers are also reasonable inputs to this function, as any negative number multiplied by itself would produce a positive number..... The output (range) would therefore be all positive real numbers......
