The exponential function y = 3(4)^x grows by a factor of 4 between x= 1 and x=2 . What factor does it grow by between x=3 and x=4

1010: 3030

is it i think

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

never fear papaguy is here
