Let A be a finite, non-empty subset of R. Prove that A has a maximum and a minimum. (Recall that a maximum of a set A is an uppe
julia-pushkina [17]

Answer:

Let us use mathematical induction to prove the statement. So, we are going to start checking the statement for the first natural numbers.

n=1: Our set is \{x_1\}. So, obviously, x_1 is the maximum and minimum of our set. Then, the statement is true for n=1.

n=2: Our set is \{x_1,x_2\}. Necessarily, x_1 or x_1>x_2. In both cases, there is a minimum and a maximum.

Once we have our statement checked for the initial cases, we state our <em>induction hypothesis</em>:

For every finite set A of n elements there exists a maximum and a minimum.

Now, let us prove the that the above assertion is true for sets with n+1 elements.

Our set is A=\{x_1,x_2,\ldots,x_n,x_{n+1}\} and we want to find

\max\{x_1,x_2,\ldots,x_n,x_{n+1}\}.

Notice that this problem is equivalent to solve

\max\{\max\{x_1,x_2,\ldots,x_n\},x_{n+1}\},

i.e, to find the maximum among n+1 numbers, we can find first the miximum among n and then compare with the other one.

Now, using our induction hypothesis we know that there is a maximum in the set \{x_1,x_2,\ldots,x_n\}, because it has n elements. Let us write

x' =\max\{x_1,x_2,\ldots,x_n\}.

So, in order to find the maximum of A, we have to find the maximum of \A'={x',x_{n+1}\}. As we have checked at the beginning, there is a maximum in A', and it is the maximum of A.

Hence, we have completed the prove for the existence of the maximum of a set with n+1 elements. The prove for the existence of the minimum is analogue, we just need to change ‘‘maximum’’ for ‘‘minimum’’.

The equations y+x^2+6x+8 and y =(x+2) (x+4) both define the same quadratic function. Without graphing, identify the x- and y-int
Goryan [66]

Answer:

we get the  

x-intercepts setting y=0 and the in the equation

y-intercept setting x=0 in the equation.

Step-by-step explanation:

x-intercepts( y=0)

0=x^2+6x+8=(x+2)(x+4)

Hence x=-2 and x=-4 ( We got two x-intercepts)

y-intercept( x=0)

y=0^2+6(0)+8=8.

the y intercept is y=8 ( only is possible to find no more thant one).
