The functions f and g are defined as follows.
f(x)=+3x+2
g(x)=−2x^3 -3
find f(−6) and g(−2)
simplify your answers as much as possible.

a² + b²= c²

24² + 7² = c²

c= 25

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
