  5.  stretch/compress

  6.  horizontal shift

  7.  vertical shift

Step-by-step explanation:

Consider the form ...

  g(x) = a·f(x -h) +k

This set of transformations is ...

__

Comparing this to your questions, with f(x) = x^2, you have ...

5.  'a' effects stretch/compress

6.  h effects horizontal shift

7.  k effects vertical shift

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!
