Question 266553
we can create a table based on the equation {{{y = -(1/5)^x}}} as
x . . . . (-3) . . . . . (-2) . . . . . (-1) . . . . . (0) . . . . (1) . . . . . . . . (2) . . . . . (3)
y . . . .(-125) . . . .(-25) . . . . (-5) . . . . .(-1) . . . .(-1/5) . . . .(-1/25) . . .(-1/125)
-----
The asymptotic line is y = 0
