im going to post attachment
there it is ^^^^
what do you think the pattern is?
for which question A. B. or C.
for the table. you need the pattern to do them all.
well i think the pattern is going by 4 right?
no. It started at 1, then added 2, then added 4, then added 8. What would be the next number added?
i think 12
Each line is adding 2 times the last number added, so when x = 5 y = 1 + 2 + 4 + 8 + 16
because 2*8 = 16
OMG!! THATS TRUEE I WAS ADDING THE WHOLE TIME THAS Y I GOT IT WRONG
you're welcome. you got if from here?
Yep i do Well Can you help me with the B part?
ok. the first thing you want to do is turn those sums into numbers like this |dw:1434049238139:dw|
from there if you know your exponents you should see the pattern. |dw:1434049509172:dw| Your y-values are 1 less than 2^x
OH yea truee
Do you mind helping me with C?
ok. how would you write the equation from the pattern we found in b?
im not shure
We have in the third column and expression for x. The second column is y. What's the relationship between numbers in the 2nd and 3rd columns?
i actually dont see a relatipnship between them at all
subtract the numbers in the 3rd from those in the 2nd and tell me what you get?
2-1=1 3-4=1 7-8=1 15-16=1
those should be -1.
so if you subtract 1 from 2^x you get y
so was that the answer?
OH WELL THANK YOU!!!
