Need help graphing exponential functions

Question

anonymous · Answer

Y=(1/2)^2x

anonymous · Answer

i dont understand what part u specifically need help in
do u want to kno how ti find intercepts, or if it is just to graph u can just plug in values

anonymous · Answer

I know how to find the intercept, it's (0,4) 
The other points I don't understand

anonymous · Answer

just plug in values in ur calculator

anonymous · Answer

1/2 life graphs are very common ull find a pattern

anonymous · Answer

When I plug the function in y= I only get the intersection

anonymous · Answer

-1..4
1..1/4
2..0.0625

$$\large y=(1/2)^{2x} = 4^{-x}$$

anonymous · Answer

I think half life expressions are more common in highschool textbooks

anonymous · Answer

it should look like this

anonymous · Answer

Or (1/4)^x
But I don't know how they got (0,1)

anonymous · Answer

Aside from (1/4)^x

(0,1) - $4^{-0} = 4^0 = 1$

geerky42 · Answer

-0 and 0 is same, it's just zero.

anonymous · Answer

(1/2 )^(2*0)=1/2^(0)=and we kno anything to power 0 is 1

geerky42 · Answer

except $0^0$, lol.

anonymous · Answer

Okay so for y=(1/2)^x-2
How did they get (1,2)?

anonymous · Answer

god tht nightmare are u taking calculus II in uni?

geerky42 · Answer

x =1 so (1/2)^(1)-2 = (1/2)^-1 = 2

anonymous · Answer

It's terrible

anonymous · Answer

y=(1/2)^(1-2)
 = (1/2)^(-1)
=2

anonymous · Answer

u flip denominator to make power positive

anonymous · Answer

That you both! I finally get it
So simple....
