Is the relation a function? why or why not? (-3, -2) (-1, 0) (1, 0) (5, -2)a. no- to domain values exist for range value -2b- yes- only one range value exists for each domain valuec- yes- to domain values exist for range value -2d- no- the relation passes the vertical line test

a=r

d=q

c=p

b=s

hope this !

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
