If the parent function f(x) = x2 is modified to g(x) = 2x2 + 1, which statement is true about g(x)?
a. it is an even function.
b. it is an odd function.
c. it is both an even and an odd function.
d. it is neither an even nor an odd function.

yes. we do proportions in probabilities.

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
