Title: State the transformations on the function f(x)= 4sin(x-pi)-2 and then graph two cycles below. Post by: marinejas on Jan 4, 2021 Using a table of values must be used in this case.

Post by: bio_man on Jan 4, 2021 Hi marinejas (https://biology-forums.com/index.php?action=profile;u=963325), before I answer this, I'd like you to review the following videos in order of importance:
Video 1 (important): https://www.youtube.com/watch?v=R1zVhbru28U Video 2 (important - this video is in degrees, but it is very helpful): https://www.youtube.com/watch?v=oNDaNg2Qh3s More: https://www.youtube.com/watch?v=PsvbplMGnoA https://www.youtube.com/watch?v=-IQnUvaOUYE Reply back once you've watched them...

Title: Re: State the transformations on the function f(x)= 4sin(x-pi)-2 and then graph two cycles below. Post by: marinejas on Jan 5, 2021 would you mind doing one more example? there's also b) to this question which is f(x)= -2sin2(x+pi)-3 I did it yesterday and just wanted to check my answer if thats ok!

Will do when I get home... Sorry about the timing Title: Re: State the transformations on the function f(x)= 4sin(x-pi)-2 and then graph two cycles below. Post by: marinejas on Jan 5, 2021 its all good :)

So what's troubling you with this question, is it the creating a table part? Best if you show us what you've done, then diagnose the problem.

Title: Re: State the transformations on the function f(x)= 4sin(x-pi)-2 and then graph two cycles below. Post by: bio_man on Jan 5, 2021 This one is more complicated because you'll need to use more x-values to get an idea of what's happening.
(https://biology-forums.com/gallery/42/6_05_01_21_1_48_29.png) (https://biology-forums.com/index.php?action=gallery;sa=view&id=42331) See my table? I used 0, pi/2, pi, etc. But you'll also have to use pi/4 increments to get a reasonable table of values.

Post by: marinejas on Jan 5, 2021 Do you mind showing me the correct chart to this question it would help me see where I went wrong

Just use your calculator to plug in those x values into each column to get the answer. Title: Re: State the transformations on the function f(x)= 4sin(x-pi)-2 and then graph two cycles below. Post by: marinejas on Jan 5, 2021 Okay I got the answer thank you!
Just to make sure, the correct transformations for this question is reflection in the x-axis, vertical stretch by a factor of -2. Horizontal compression by a factor of 1/2. Phase shift pi units left. Equ of axis is y= -3 |
