[viral sorrel]

Idk how to do it

[half gulch]

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

finally someone

[devout sky]

so a vertical stretch is just multiplying your whole function by 8

for this

which gets you 8sin(x)

then to get your horizontal compression you want to make it take ⅕ times larger x to get the same value as if it wasn't compressed

so now we have 8sin(5x)

nvm 5

[viral sorrel]

uh huh

keep going

[devout sky]

for a horizontal shift left you want it to reach day sin(x)=0 at sin(x+3π/20)

so now we have 8sin(5(x+3π/20))

and a translation up is just adding 4

[viral sorrel]

then +4?

[devout sky]

8sin(5(x+3π/20))+4

[viral sorrel]

says its incorrect, i've been trying for a couple days

@devout sky

[devout sky]

you didn't put 8sin...

[viral sorrel]

still

[devout sky]

try 8sin(⅕(x+3π/20))+4

[viral sorrel]

nope

[devout sky]

bro it's been so long since I last did this

sorry

give me a sec to actually do the workings

[viral sorrel]

kk

[devout sky]

y=8sin(5(x+3π/20))+4

[viral sorrel]

sigh

[devout sky]

the wording of that problem is wildly different to anything I've been taught

[viral sorrel]

even when simplifying

[devout sky]

do you have your notes?

[viral sorrel]

there online give me a sec

[devout sky]

horizontal compression by ⅕, is that a stretch by 5 or a stretch by 0.8

it's way different to all the translation problems I've done

[devout sky]

then it should be y=8sin(5(x+3π/20))+4

but apparently that's wrong, sorry

[viral sorrel]

yg bro

prob just an error on my teachers end

im grateful for you

[devout sky]

try fully simplifying this to y=8sin(5x+3π/4)+4

[viral sorrel]

tysm

[edgy heath]

@glossy matrix has given 1 rep to @devout sky

[devout sky]

💀

[viral sorrel]

simplification error is so sad

[devout sky]

weird ass wording

I hate your prof

[viral sorrel]

hate?

[devout sky]

dislike

[viral sorrel]

you're a good guy

[viral sorrel]

i pray for you and wish the best for you, even though i dont have a clue what that is

[devout sky]

thank you, good luck with your work
