Question 28 on this pictured math sheet please. Have a great day!

A rectangular array of numbers arranged in horizontal and vertical lines enclosed between round or square brackets is called a matrix.

Types of Matrix

According to order of matrix or value of elements,we can classify the matrices. some of the types of matrices are as follows:

Column Matrix

A matrix having only one column is called a column Matrix.

Row matrix

A matrix having only one row is called row matrix.

Square matrix

A matrix having the numbers of rows equal to the numbers of column is called the square matrix.

Rectangular matrix

A matrix having the number of rows not equal to the number of column of a matrix is called the rectangular matrix.

Null matrix( zero matrix)

A matrix of any order in which each element is zero is called the null matrix( zero matrix).

Diagonal matrix

A square matrix in which all the elements of leading diagonal are non-zero and the rest of the elements are zero is called a diagonal matrix.

Unit matrix( Identity matrix)

A diagonal matrix in which all the elements of leading diagonal are 1(unit) is called unit matrix.

Scalar matrix

A diagonal matrix in which all the element of leading diagonal are equal is called scalar matrix.

Triangular matrix

A square matrix having all the elements below the diagonal and above the diagonal zero is called triangular matrix.

Symmetric matrix

A square matrix is called a symmetric matrix, if it's

(i,j) th element is equal to its (j,i) th elemnent.

Skew-symmetric matrix

A square matrix B=b ij is called a skew- symmetric matrix if it's (i,j) th element is negative of its ( j, i) th element.

Equal matrix

Two matrices are said to be equal if they have same order and corresponding elemnents of both matrices are equal.

Hope this helps..

Good luck on your assignment...

Answers: the graph is translated down 1 unit and the domain and range of g(x) is the same as the domain and range of f(x).

It would be very great if u would let me take your dog home forever you i love you ti so much carmen you don’t even know bby
