Which is the graph of the sequence defined by the function f(x) = 100(0.5)x - 1?

On a coordinate plane, 4 points are plotted. The points are (0, 100), (1, 50), (2, 25), (3, 12.5).

answer: this is hard

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
