State the domain of the sets of points. [-4,9] [8,9] [5,-7] [-6,1] [2,7]

[-6, -4, 2, 5, 8]

Step-by-step explanation:

take the first number in each pair and put them in numerical order (least to greatest)

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
