If f(x) = 6x + 2, which of the following values would complete the table shown?

16 and 64
0 and 1
64 and 70
14 and 50

f(x) = 6x + 2 f(2) = 6(2) + 2 f(2) = 12 + 2 f(2) = 14 f(8) = 6(8) + 2 f(8) = 48 + 2 f(8) = 50 Answer Is : 14 and 50

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
