A- Emily gave exponential equation y = 3^x . it is incomplete equation .with this we do not get table values of y.

for example 3^0 = 1 while y = 0.

B- correct equation is

y = 3^x - 1

C- proof

y = 3^0 - 1 = 1 - 1 = 0 (0 , 0 )

y= 3^1 - 1 = 3 - 1 = 2 ( 1 , 2 ).

y= 3^2 - 1 = 9 - 1 = 8 (2 , 8).

y = 3^3 - 1 = 27 - 1= 26 . ( 3 , 26).

y =
