Question

please help!! logarithms

Answer 1

g(x) = 3f(x)

Answer 2

i don't understand which it could be. >.<

Answer 3

okay, so when f(x) = 0 then x = 1. Can you understand who I got that answer?

Answer 4

no. /.\

Answer 5

f(x) = 0 = 3log_10(x)

Answer 6

0=log_10(x)

Answer 7

x=1

Answer 8

which means that when x=1, f(x) = 0

Answer 9

oh oke.

Answer 10

using the same method we can show that, when x=0, g(x)=0

Answer 11

can you see how I got that result?

Answer 12

yes.

Answer 13

it should be when x=1, g(x)=0

Answer 14

which means both f(x) and g(x) graphs should go through the point (1,0)

Answer 15

So any of the shifting is not an answer

Answer 16

now we are left with only two possibilities; either stretching or compressing.

Answer 17

it stretches. c:

Answer 18

right

Answer 19

I hope you got the idea

Answer 20

i did! thank you.

Answer 21

cool
