HELLPPP MEEE PLS:<

domain is the first number in the set, codomain is the second number.

eg range for 1. 3<x<9

do this for the rest of ur questions

it is only a function if it is a one to one or a many to one relationship. one domain Must be only connected to only one codomain

Step-by-step explanation:

hope u can derive the answer from the above explaination.

the 4th choice is the correct one

step-by-step explanation:

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
