wouldn't this be differentiation? use the power rule which should give y=2x+5 then sub in your x value which is 1 which gives you the gradient of the tangent (7)
then substitute x=1 into the original equation to find the y intercept at x=1 which should be y=12 which gives you the point where the tangent touches the parabola (1,12)
then use point slope form y-y1=m(x-x1) and sub in your values
y-12=7(x-1)
y-12=7x-7
y=12+7x-7
y=7x+5
which is the equation of the tangent to the curve
and the normal is just perpendicular to that which should be y=-1/7x+5
sorry if my explanation is unclear but i checked in desmos and it looks right

ohhh ok got it got it tysm!!

 

[hi_998]

yeah i asked my math teacher and her response was
and i quote "looks like stuff from the advanced course"
like ok??? clearly people are doing it in year 10 so ????

hey! im not doing it at school lol. im moving to sghs next year and want to be ahead in math rather than struggle to keep up so ive asked my tutor to start topics on advnaced math

how do i do this?

Thats what im meant to be studying rn too
I have an exam in week 9 n i havent even started
Guys i have like 5 assignments n 2 tests all due in the same week n im so stressed idk what to do

History: idk how to analyse shit

English: dont understand the assignment, my teacher doesnt know how to explain the assignment n i havent finished the book yet

STEM: its group so i have to rely on other ppl

PE: its a dance assignment n my group is still deciding on verse 1 MAN WE HAVE MORE THAN JUST VERSE 1 TO MAKW A DANCE FOR

Commerce: its group n my group didnt do shit uk that i have to make a 24 slide by myself bc my team isnt doing anything n i cant tell the teacher bc she’ll mark us down for not disturbing the work equally

Math: im so behind on my hw i need to do my hw before i revise for my test

Science: got it today but its a physics test n i need to do everything else before

ik im ranting but guys i rlly need help im so stressed n dont know what to do (note i have started history n eng)

why u so sassy bruv
your teacher is correct in saying that it's from the advanced course since as far as I can tell, you'd need differentiation for this question
differentiation is only taught in the yr11 advanced course
people doing it in yr10 are doing yr11 work early, it is NOT in the yr10 course

fuck i'm so cooked i've got no clue and i'm in 5.3...
i guess that's what happens when you go to a public high

nothin to do with public school, same reasoning as above

i legit only have math this term(test was yesterday), science is an irp so that doesnt count and every other subject i just dont have any assessments

lol???? you got the messages in the wrong order um i only say because the way you've quoted it makes it look like i was complaining after i asked haha
and also,

Thats what im meant to be studying rn too

talking about the math? is jane also studying early???
anyway

nah apparently our teacher intertwines a lot of advanced math topics for us to do in our studies like rn we studying non-linear relationships

 

[jane1820]

anyways the trains schedules for today were so fucked up apparently bc someone suicided at redfern
istg if any of u every suicide at redfern imma jump u n i dont care if ur already dead

 

[Socialism]

bruhhh I want to do advanced sooo bad but how can i compete with y'all already doing it???? and im not concentrating hard enough either its like my only bad subject...

ok socialism

sorry sorry sorry sorry

wasnt he just standing on the tracks i dont think he killed himself

 

[jane1820]

wasnt he just standing on the tracks i dont think he killed himself

literally dont know n dont care maybe if he didnt fuck the train schedules i wouldve

damn i used to take the train to central for school, if that happened to me I'd be so pissed omg.

We can all help if ur struggling! Maths is abt understanding and how much effort ur willing to put. Even though you feel that people are ahead of you, that shouldn't stop you from trying.
