anonymous · Answer

hi and sure I'll try if you return the favor as well

jasmineflvs · Answer

im not that high in math im asking a question for my friend

jasmineflvs · Answer

the graph y > x^2-6x +7 contains which points

anonymous · Answer

is x^2 means radical 2? i wanna get clear on that

jasmineflvs · Answer

i think it means squared

jasmineflvs · Answer

plzz help

anonymous · Answer

okay so substitute y=0 so the equation should be 0=x^2-6x+7

jasmineflvs · Answer

okay anything else

anonymous · Answer

i hope this is what you're looking for

jasmineflvs · Answer

k thanks

anonymous · Answer

mhm good luck!

anonymous · Answer

someone there to help me??):

anonymous · Answer

so the arclenght is equal to 2pi*radius, im not sure how the radians come into play

jasmineflvs · Answer

okay just a sec it was supposed to be the graph y= x^2-6x +7 contains which points and the ^ after the x means squared

directrix · Answer

@Jasmineflvs   What are the points which are options to the question:

y= x^2-6x +7

anonymous · Answer

do you know the website wolframalpha? i used that a lot for my math hw

jasmineflvs · Answer

idk Directrix

jasmineflvs · Answer

I am working on what to post to help you see the answer. Just a sec.

jasmineflvs · Answer

okay

jasmineflvs · Answer

cause he needs it soon

directrix · Answer

y= x^2-6x +7
Let's test the point (3,-1)

Substitue 3 for x and -1 for y.

IS -1 > 9 - 6*3 + 7

-1 > -9 + 7    Yes or No  @Jasmineflvs
