Question

1. Sketch the graphs of the two functions f : [0, π] → R, g : [0, π] → R where
f(x) = sin(3x), and g(x) = 5 − 4 sin(3x).
Explain carefully how you obtained the graph y = g(x) from the graph of y = f(x).
(a) Write down the ranges of both f and g.
(b) Is f one-one on this domain? Justify your answer.
(c) Indicate an interval on the x–axis where f has an inverse. Justify your answer.
(You have not been asked to find this inverse.)
2. Sketch the graph of the following piecewise function
f(x) =

.
Let g(x) = −f(x) and h(x) = 1 − f(x). Add the sketches of y = g(x) and y = h(x) to
your picture. 

Expert Solution
Step 1

"Since you have asked multiple questions, we will solve the first question for you. If you want any specific

question to be solved, then please specify the question number or post only that question."

 

First we will sketch the graph of the function fx=sin3x. Then, we will use the transformation to

graph the function gx=5-4sin3x.
