What transformation has changed the parent function f(x) = log3x to its new appearance shown in the graph below?

logarithmic graph passing through point negative 1, 3

Select one:
a. f(x + 4) + 2
b. f(x − 2) − 2
c. f(x + 2) + 2
d. f(x − 4) − 2

It is f(x + 4) + 2. I just took the test and that was the answer.

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
