Adjust the domain so goes to

Just rearrange to solve for x.




From above has a period 3. So from this, and by drawing a quick graph, it has a maximum at
For the vertical translations don't affect x value in this case. Since it's been translated 1 unit to the right, the maximum must be

ahhhh i get it, except for one part; how did you change the domain?
I was able to solve it without doing so but I'm just curious :p
...I know the exam is in like, 1.5 hours lol but I'm just curious :) If anyone is awake to show me I'd be grateful!

You dont really need to adjust the domain.

But you see the original domain is [0,3]


the 0<x<3

u times 2pi/3 into x
whatever you to do x
you to '3' and '0'

therefore

2pi/3  x   3
= 6pi /3
= 2pi
therefore 0<2pix/3 <2pi

Bucket is that really you in the picture? i really wanna punch you in the face LOL :D

How do you do this?? Note this is from a CAS exam.

HAHA. I just did this question.
The best way is to solve for a,b,c,d,e on ur cas using matrices.
We know that a=.1 and c=3.9
Therefore, c=39 x .1
               c = 3.9
    Hence, c=39a   
So the answer is D.

The graphs of intersects the graph at two distinct points for:

a.
b. or
c.

e.

How do I work this out quickly?
