Question

Which ordered pairs lie on the graph of the exponential function f(x)=3(1/4)^x ? Select each correct answer.

(−2,48) ​

​ (0,3) ​

​ (2,316) ​

​ (12,0) ​

Answer 1

-2,48 and 0,3

Step-by-step explanation:

I was doing the k12 test and when I finshed it I got it right

Answer 2

Options 1 and 2

Step-by-step explanation:

We nee to check which points are satisfying the given function
`f(x)=3((1)/(4))^x`

In case 1 we will pu x= -2 in given function we will get
`(3)/(1/16)`=48

Hence, option 1 is correct

In case 2 we will put x=0 in given function we will get
`3((1)/(4))^0=3`

Hence, option 2 is correct

In case 3 we will put x=2 in given function we will get
`3((1)/(4))^2= (3)/(16)`

Hence, not satisfying the function so incorrect

In case 4 we will put x=12 in given function we will get
`3((1)/(4)})^(12)`
`=3((1)/(16777216))\\eq0`

Hence, not satisfying the function so incorrect.
