Q:

Describe how to transform the graph of g(x)= ln x into the graph of f(x)= ln (3-x) -2.

Accepted Solution

A:
Answer:AStep-by-step explanation:Note the following 3 points with respect to a function given as y = f(x).1. The function y = f(-x) is a reflection across the y-axis2. The function y = f(x+a) is a horizontal translation a units left and y = f(x-a) is a horizontal translation a units right3. the function y = f(x) + a is a vertical translation a units up and y = f(x) - a is a vertical translation a units downDissecting the transformed function of  f(x) = ln (3-x) -2   w.r.t   f(x) = ln x, we see:1. x is replaced with -x, so reflection across y-axis2. we have a horizontal shift in left side because the argument of ln is (3-x) or (-x+3)3. We have vertical shift 2 units down because there is a -2 after the functional part of ln(3-x)Looking at the choices, A is the right answer.
