Question

Please explain how you got the answers also please. Thank you :)

Answer 1

x = -2 —> y = 4

x= 0 —> y = 1

x= 3 —> y = 1/8

Explanation:

X= –2

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

X= 0

`y = ( (1)/(2) ) ^(x) \\ y = ( (1)/(2) ) ^( 0) =1`

X= 3

`y = ( (1)/(2) ) ^(x) \\ y = ( (1)/(2) ) ^( 3) = \frac{ {1}^(3) }{ {2}^(3) } = (1)/(8)`

I hope I helped you^_^
