Please help today is my birthday !!! part A: Without using a graphing calculator, which equation could be represented by the accompanying graph?

Question 10 options:

y=2^x

y=2−x

y=x^2−2

y=−2^x

Part B: Explain how you selected the equation in Part A

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
