Chapter 2: Q36E (page 126)

How many different elements does A X B X C have if A has m elements, B has n elements and C has p elements?

Short Answer

Expert verified

\(m \times n \times p\)

Step by step solution

01

Number of elements in a set

If X is an element of Y

Notation:\(X \in Y\)

The number of elements in it will be \(x \times y\) .

02

To find different number of elements

Number of elements in set \(A = m\)

Number of elements in set \(B = n\)

Number of elements in set \(C = p\)

Therefore, number of elements in \(A \times B \times C = m \times n \times p\)

Question: Which function in exercise 12 is onto?

Find the output of each of these combinatorial circuits.

Determine whether each of these functions is a bijection from R to R.

  1. fx=-3x+4
  2. fx=-3x2+7
  3. role="math" localid="1668414131444" f(x)=(x+1)/(x+2)
  4. role="math" localid="1668414147841" fx=x5+1

a) define the union, intersection, difference, and symmetric difference of two sets.

b) What are the union, intersection, difference, and symmetric difference of the set of positive integers and the set of odd integers?

Let f:R→R and letfx>0 for all x∈R. Show that f(x) is strictly decreasing if and only if the functionrole="math" localid="1668414965156" gx=1/fx is strictly increasing.
