Plzzzz help asap

Which ordered pairs lie on the graph of the exponential equation f(x)=3(1/4)^x?
Select each correct answer.
​A. (−2,48) ​

​B. (0,3) ​

C.​ (2,3/16) ​

D​ (12,0) ​

Answer 1

(x,y) or
(x,f(x))
so just plug the first value in and see if yo get the 2nd value


A. when x=-2, then is f(x)=48?
remember, x^-m=1/(x^m)
3(1/4)^-2=3/((1/4)^2)=3/(1/16)=3*16=48
true

B. x^0=1
so 3(1/4)^0=3(1)=3
true

C. when x=2
3(1/4)^2, 3(1/16), 3/16
true

D. 12
das is obviously false but anyway
3(1/4)^12=3(1/big number)=3/big number=small number but not zero



answer is A,B,C
