I hope school is going well for everyone in isolation. :dizzy:

Iā€™ll try to help out with any question as best as I can. :nerd_face:

Here are some sites I frequently use when studying maths (in case anyone is interested heh): symbolab.com, desmos.com and geogebra.org.

rip, can anyone help with a math problem?

Nevermind, Iā€™m good now

I need help lol. My brain isnā€™t working for simple algebra. Ok so basically if the y intercept is 8, and thereā€™s -2x and thereā€™s also -.98 Iā€™d go up 8, down 2 then over .98 right?

Hey, would love to help but I donā€™t understand your explanation.

Could you send the question? :smiling_face:

(If you havenā€™t solved it yet)

Itā€™s a complicated problem actually but I got confused about the graphing aspect of it lol. Iā€™ll attempt to send it however it has some stuff that I cannot/do not know how to put here:
So Iā€™m supposed to make a graph about this problem and identify how it is different from itā€™s parent function:
y= 8*-1
(*= x lol but couldnā€™t put it up there with the 8 cuz my keyboard doesnā€™t do that lmao)
So I made a table of values
when x= -2 y= -.98
x= -1 y= -.88
x= 0 y= 0
x=1 y= 7
this kind of threw me off because the numbers are just weirdā€¦ especially jumping from one to 7 but I tried to roll with it yet the graph kinda looked weird. So I donā€™t think I did it right lolā€¦ umā€¦

Thatā€™s a really weird keyboard :joy:

If the function is:
y = 8x - 1

I kind of donā€™t get the numbers you get. It should be a straight light with the slope 8 and cutting the y-axis in -1.

Iā€™m the point x = -2, y should be y = -17, not sure where you got -.98 from.

I might be reading the function wrong.

Or waitā€¦ the parent function? What does that mean? Is there another function involved? Lol

Oh noā€¦ Lol the x in the problem is above the 8.

like think of 8 to the second power, well this is Y= 8 to the x power -1

Lol yay I found the name!

Oh okay lol! So y = 8x^-1 ?

76

Waaait, you mean y = 8 to the power of 1/x ?

(Gotta get this function straight to help lol)

SO like in graphs, thereā€™s a ā€œgenericā€ graph function thing, and itā€™s gonna be this generic position, and then when you change things on the graph it changes.

So like from looking at certain numbers you can tell if the slope is gonna be positive or negative, go up or down and even where to place stuff.

Closer? x IS the power, and the power is unknown. So pretend * is a little x. 8* - 1

lol if you havenā€™t heard of logarithms before/donā€™t remember/know them then I probably canā€™t use your help unfortunately.

Okay, so what is the problem? Finding the min and max of the function? Or just plotting it?

Do you have a graphing calculator?
