Question

I WILL FAN AND MEDAL


Which of the following options results in a graph that shows exponential growth?

f(x) = 0.4(0.2)x
f(x) = 4(0.98)x
f(x) = 0.7(5)x
f(x) = 5(4)−x

Answer 1

none of them
from the way it is written

Answer 2

denote exponents by using ^ sign

Answer 3

ok

Answer 4

yeah on the question in the actuall lesson all of the x things are exponents

Answer 5

there is a big difference between \[0.4(0.2)x\]
and \[0.4(0.2)^x\]

until you make it clear, no one can solve this

Answer 6

its the raised one
it just copied and pasted weird

Answer 7

however, i still dont know if the problem is suppose to look like
\[0.4^{(0.2)}x\]

Answer 8

copy and paste will not write in expoents for you

if the number/variable is raised
then you should put a ^ infront of it

Answer 9

no only the x on all equaions are raised

Answer 10

so 2^x would look like
\[2^x\]

Answer 11

yes

Answer 12

something with \[2^{-x}\] means a exponential decrease
and is equivalent to
\[(\frac{1}{2})^x\]

Answer 13

im not sure i understand.. math isnt my best subject

Answer 14

numbers to the expoential x that are greater than 1, are exponentially increasing
numbers with the exponent x that are less than 1 , are exponentially decreasing
ex.\[3^x --- increasing\]
\[.3^x --- decreasing\]

Answer 15

its the opposite if the exponent is to the -x (negative x)

Answer 16

ok
so it would be one of the last two?

Answer 17

or sorry

Answer 18

b and d

Answer 19

hello?

Answer 20

are both incorrect

Answer 21

no a and c are incorrect

Answer 22

i just need to know if its b or d

Answer 23

well, my answer would be C

Answer 24

ok

Answer 25

f(x) = 0.7(5)x?
