Use function notation to solve.

If f(x) = 5x-6 then find f(8)

f(8) is 34

Step-by-step explanation:

8*5 is 40, and 40 - 6 is 34

34

Step-by-step explanation:

f(x) = 5x-6 then find f(8)

f(8) = 5(8) - 6

f(8) = 40 -6

f(8) = 34

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
