Jen has collected information about the students in her class and the month they were born. which of the following statements would be true about this information? a. it is both a relation and a function. b. it is a relation but not a function. c. it is not a relation, but it is a function. d. it is neither a relation nor a function.

a

step-by-step explanation:

it's both a relation and a function.

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
