Question

.

Answer 1

y intercept = -1
x intercept = ln(1/2)/ln(3)

asymptote => x = -1

Answer 3

yea ... yea

Answer 4

take limit x->inf
and limit x->-inf

if it converges, or has a limit than that is your asymptote ... and sorry about wrong asymptote ... the asymptote is y = -1 not x = -1

Answer 5

it's not in the graph ... as x tends to - infinity ... y tends to -1 ,, so y = -1 must be your asymptote

Answer 6

no, as you decrease the value of x ... to negative infinity, y -> -1

Answer 7

just what might be the value of y =2(3^-10) − 1 ... the more you decrease x, y comes closer to -1

Answer 8

no, you decrease x, x=-1,-2,-3, ...-100, .... -10000 and y comes closer to -1
