look for x=0
that is the point where graph cuts y=axis
from equation,
y= 3*1.9^0 = ... ?
OpenStudy (anonymous):
wait
hartnn (hartnn):
which one is C ?
the middle one ?

I sit B
hartnn (hartnn):
when x increases, the value of 4 (3)^x also increases.
also, at x=0, y= 4(3)^0 = 4
from these you can say that its B, yes.

Is it A
hartnn (hartnn):
st, x=0, y=... ?
hartnn (hartnn):
yes, that graph iss correct.
OpenStudy (anonymous):
option A looks similar

yeah, it looks similar, but the intersection there is around y= 3 instead of y= 0.2 or 1/5
hartnn (hartnn):
its not B or D for sure.
OpenStudy (anonymous):
about this graph
hartnn (hartnn):
yes, its that graph.

wrong
hartnn (hartnn):
