Which is true about the domain and range of each function

the range of a function is the set of results solutions or output values (y)to the equation for a given input. to be honest a function only has one result for each domain.  

Step-by-step explanation:

R there answer choices?

a

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
