None of it..

anonymous · Answer

-1

anonymous · Answer

Are you sure your equation is not:

y = 2x + 3  ??

anonymous · Answer

is that

anonymous · Answer

@best.shakir can you show how you got -1 ??

anonymous · Answer

it has to be one those are all the answers on the  multiple chose the x is a exponet

http://www.wolframalpha.com/input/?i=find+y-intercept+of++y%3D2%283%29-x%3F i am not satisfied with this ans

anonymous · Answer

@best.shakir it is better for you if you will use wolfram alpha for problems harder than this..

You always provide that link..

Try to do it here on your own..

my steps will not understand to everybody.so that i m sending links

anonymous · Answer

Yes, please stop citing web resources. I have yet to see an answer that does not involve a direct link to a web resource.

If you can arrive at an answer it should be explainable.

anonymous · Answer

i know that wolfram sometimes will make wrong ans

anonymous · Answer

@greener6 is it ??

$$\large y = 2(3)^{-x}$$

anonymous · Answer

yes

anonymous · Answer

so it has to be 2 right

anonymous · Answer

So anything raised to the power except 0 is 1..

So:

$$y = (2)(3)^0 \implies 2 \times 1 = 2$$
