Answer 2

d,

Answer 3

please elaborate ^^^

Answer 4

heya sat73

Answer 5

looks like \(k=-3\)

Answer 6

Could you please describe how you got the answer?

Answer 7

oh sorry, yes thats right

Answer 8

ok

Answer 9

the h. asymptote

Answer 10

Getting late for me... hah..

Answer 11

then we have \[y=ab^x-3\] and we also have
\[f(0)=-2\] so
\[a-3=-2\] making \(a=1\)

Answer 12

now we are at
\[f(x)=b^x-3\] and \[f(-1)=b^{-1}-3=-\frac{3}{2}\]

Answer 13

that makes
\[\frac{1}{b}=\frac{3}{2}\] or \[b=\frac{2}{3}\]

Answer 14

ahh okay!
