I know this is a lot but please help me, it is my last question and I would give you a medal AND BECOME YOUR FAN and a testimony. You have no idea how much you would help me just by doing this. #savealife
@mathmath333
giiirrrllll uz gotz ppl hittin u up left and right u good? imma let them help u:)
All you have to do is input the number in for x and solve. EX: -2(-2)^4 PEMDAS says we solve exponents first, so -2^4 is 16 -2(16)=-32 You do this with all of them, and then graph them. Remember, the equation of a line is y=mx+b m=slope b=y intecept
tHAT IS FOR B?
Thats for the first blank in the chart, aka the y value for x point -2
agh that is so confusing ;-;
In order to solve for m and b, you have to use a different formula. y1-y2=m(x1-x2) So, I gave you one set. Can you do what I did and get a second set of points?
Ok, lets go back. Do you understand how I got -32 as the y value for -2?
is it -8?
For which x point?
the f(x) part, the lower part of the chart
Right, but on -1, 0, 1 or 2?
-1
I got -2. -2(-1)^4 -2(1) -2 Show me what you did so I know what you're doing wrong.
i multiplyed -1 by 4
and then by -2
Ok, the 4 is an exponent. Which is kind of multipication, but in a different way. Instead of 1(4) it is actually 1x1x1x1. 1 times anything is the other number, or in this case 1x1=1.
Now that you know that, do the remaining 0, 1 and 2 and tell me your answers. I will check them for you, and then we can go over how to graph the numbers.
ah okay
0 , -16, 256
@potatoprincess22
-2(0)^4 -2(0) 0 Good -2(1)^4 -2(1) -2 Show me what you did here please -2(2)^4 -2(16) -32 Show me this one as well
i multiplyed it all of those numbers by the 2...like the two and waht is inisde the perenthases , and then I took that number... and x4 as in, 16 x 16 x 16 x16
the chart, I know it starts at zero and then it goes parallele to each other down right> ?
It is a parabella (I dont know how to spell it, sorry), so it will form an upside down U.
0 will be the peak
ah I got it :) but how about c?
On the x and y coordinates we just went over, you want to always follow PEMDAS. Exponents come before multiplication. Im going to assume C means what kind of graph it is, which is a parabella. Basically a parabella is a graph that has 2 xs for each y, like is shown in this graph. Do you understand what we did or do you have more questions?
NO THANK YOU SO MUCH X
Great job, I gave you a medal because even though you got most of what you did on your own wrong, you tried. I hope what I showed you helps. And if you find that you are still struggling make sure you go to your teacher privately! They are the best tool available!
My teacher lives far away from me haha because I attend an online school
BUT THANK YOU. i gave you a medal too xD
Oh, so do I! You can still always call them or send then an email!
And, its no problem! :D
