Question

f(x) = 10^-x

Answer 1

All real numbers.

Answer 2

what do you want?

Answer 3

oh oops. i need to graph it

Answer 4

derivate or integrate?

Answer 5

not sure

Answer 6

what class are you in?

Answer 7

f(x)=1/10^x

Answer 8

pre cal

Answer 9

What is f(0)?

Answer 10

thats wrong
so eventually 0=0 which the equation does not exist

Answer 11

0/x=45 WRONG

Answer 12

f(0) means value of f when x is 0

So what is f(x) = 10^-x when x is 0?

Answer 13

f(x) will equal 1 is x is 0

Answer 14

How about f(1)?

Answer 15

=10

Answer 16

So, r u saying that 10^1 and 10^-1 are the same?

Answer 17

wait 1/10

Answer 18

f(-1)=10

Answer 19

That's better.

So u want to graph this equation, u do f(0), f(-1), f(1) and some few others until u see what is going on and then put them on graph.

Answer 20

thanks. so how about e^-2x

Answer 21

All exponential graphs look alike

Answer 22

so if i have f(x)=2^x+1 would my point be (0,2)?

Answer 23

Yup

Answer 24

cool thanks. I think its finally sticking in my brain. I think I try to make things more difficult then they have to be.

Answer 25

one more if you don't mind.

Answer 26

f(x)= e^-2x

Answer 27

if x=-1 would f(x)=7.39

Answer 28

Same game.

Answer 29

cool
