Question

Can someone help for a medal and fan?

Answer 1

Sure.

Answer 2

The graphs of four exponential functions are shown below:

Answer 3

Which pair of graphs should be plotted to show the solution to 1 over 2 (3)x = 2 (1 over 2)x?

Answer 4

1/2(3)x=1/2x?

Answer 5

AW... sorry, wrong graph

Answer 6

Or, picture I mean

Answer 7

is that your equation?

Answer 8

Thats the graph. Sorry XD

Answer 9

Close, there is a 2 infront of the second 1/2

Answer 10

1.5x=x? (solved)

Answer 11

.5x = 0

Answer 12

x = 0

Answer 13

Okay, so the options are:

Graphs P and Q

Graphs Q and R

Graphs R and S

Graphs P and S

Which one would it be?

Answer 14

I really have never done exponential functions yet soo.

Answer 15

Sorry

Answer 16

Its okay :(

Answer 17

can you just repeat the question

Answer 18

Okay

Answer 19

The graphs of four exponential functions are shown below:

Answer 20

Which pair of graphs should be plotted to show the solution to 1 over 2 (3)x = 2 (1 over 2)x?

Answer 21

ok.... and

Answer 22

Thats it?

Answer 23

ok... so are the functions

\[\frac{1}{2} (3)^x\]

and

\[2(\frac{1}{2})^x\]

Answer 24

Yup

Answer 25

ok... so you need to find where they intersect

here is an easy solution. graph them using this site

https://www.desmos.com/calculator

just enter

y = 1/2(3)^x

and

y = 2(1/2)^x

Answer 26

this will show where the point of intersection is...

Answer 27

So, do they intersect at 4,32?

Answer 28

no, here is my input, graphs and point of intersection

Answer 29

Mine looked waaaayy different

Answer 30

do you think you can identify the 2 curves now

Answer 31

Okay, I typed it in again and I got the same as you now

Answer 32

Probably.

Answer 33

ok, good luck

Answer 34

Would the answer be graph Q and R?

Answer 35

have a look at the y-intercepts in the file I attached... they are 2 and 1/2

so I'd select P and S

Answer 36

Ooooh, okay. I see now. Thank you!
