Question

write an equation for this relation: {(1,2), (2,4), (3,8), (4,16), (5,32)
*this is algebra 1problem

Answer 1

\[2^1\]

...
\[2^3\]

...

Answer 2

umm it has to be in a equation

Answer 3

i'm showing you a pattern

Answer 4

you need to realize the pattern before you can make an equation

Answer 5

these are the points you gave me
\[(1,2^1);(2,2^2);(3,2^3);(4,2^4);(5,2^5)\]
what do they have in common?

Answer 6

okay so far i see that the patter is increasing the exponent...

Answer 7

\[y=2^x\]

Answer 8

well... i gave you (1,2), (2,4), (3,8), (4,16), (5,32) these...

Answer 9

how can it be y=2^x?

Answer 10

yes thats right you gave me:
\[(1,2^1);(2,2^2);(3,2^3);(4,2^4);(5,2^5) \]

Answer 11

x=1 => y=2^1=2
x=2 => y=2^2=4
x=3 => y=2^3=8
x=4 => y=2^4=16
x=5 => y=2^5=32

Answer 12

oops... sorry... i didnt realize it

Answer 13

so its y=2^x?

Answer 14

thanks so muchh!!!
