?




​(1,1)​

​(0,0)​ ​

​​(4,−25)​

​​ (−1,2)

Answer 1

It says a different answer on line

Answer 2

( 1 , 1 ) and ( 4 , - 25 ) lie on the graph

Explanation:

f(x) = -
`3^(x-1)` + 2

( 1 , 1 ) lies on the graph

f(1) = -
`3^(1-1)` + 2 = - 1 + 2 = 1

( 0 , 0 )

f(0) = -
`3^(0-1)` + 2 = -
`(1)/(3)` + 2 > 0

( 4 , - 25 ) lies on the graph

f(4) = -
`3^(4-1)` + 2 = - 27 + 2 = - 25

( - 1 , 2 )

f( - 1 ) = -
`3^(-1-1)` + 2 = -
`(1)/(9)` + 2 < 2
