Question

Which functions in the table attached give values that could come from exponential functions? Check all that apply.

A. k(x)
B. g(x)
C. f(x)
D. h(x)

Answer 1

ok since i dont have a calculator the best guess would have to use something like this

e ^ x since its exponential

Answer 2

which one is e^x?

Answer 3

we are assuming that all are but we need to put in points to see if they match with the table if they dont match then that one is not an exponential function

Answer 4

okay and exactly which numbers do we plug into what? :o

Answer 5

like i said before use the easiest points like 0, 1, -1 and put them in the e^x
remember that e is a number

Answer 6

ok here are the functions
3 * e^ x
e^ x
e^x
and x * e^x those are possible equations

Answer 7

so for the first one, it would be in the calc 3 * e ^ 0 = 3 that checks but you need to check more points

Answer 8

so e is either 0, 1 or -1?

Answer 9

sorry, im limited since i dont have a calc
look at your x values on the table, they go from -3 to 3
we usually use those since they are the easiest to calculate thats all

Answer 10

Ali you got calc?

Answer 11

no :(

Answer 12

Dx um you go with numbers multiplying?

Answer 13

good*

Answer 14

if theyre not too big then yeah :p

Answer 15

xD well get ever number under x=1 got example

Answer 16

for*

Answer 17

g(x)

Answer 18

when x=1 g(x) is 2 correct?

Answer 19

yes because 1 is in the box? :o

Answer 20

yes so that is your base

Answer 21

so it is 2^x

Answer 22

know that is for g(x)

Answer 23

know pick another x from the chart

Answer 24

now*

Answer 25

f(x) ?

Answer 26

Dx do you want answer or you want me to explain xD?

Answer 27

both :o :p

Answer 28

xD answer is g(x) and K(x)

Answer 29

now get all the X=1 for k(x) g(x) f(x) H(x)

Answer 30

lol wutttt

Answer 31

when x=1 what is
k(x)
g(x)
f(x)
h(x)

Answer 32

4.95, 1.25, 2, 0.25 ??

Answer 33

ok so those are your bases

Answer 34

now you square all by x

Answer 35

4.95^x
1.25^x
2^x
0.25^x

Answer 36

those are your exponential functions

Answer 37

ohhhh i see

Answer 38

now you just finish out which are true and which are false

Answer 39

wait O:

Answer 40

i think its just g(x) lol

Answer 41

whtat? :O

Answer 42

wen you have e^x and x=0 the answer will always be 1 xD

Answer 43

so that means that k(x) is wrong?

Answer 44

looks like it Dx

Answer 45

might be wrong though T-T

Answer 46

its g(x) and f(x) :O

Answer 47

Dx how is it f(x)

Answer 48

no idea :O

Answer 49

unless they moved the graph up o. o
