Can we do the first one:
OpenStudy (howard-wolowitz):
what are you thinking dude
OpenStudy (campbell_st):
well in the point you have y = 0 when x = -3.... so y muse be either greater than or equal to zero or less than or equal to...
so that eliminates choices 1 and 4
so you have the middle 2 to select from.
so substitute x = -3 and y = 0
so is
0 < 6 option 2 or 0 > 6 option 3
you decide
OpenStudy (campbell_st):
the next question
is interesting sin < 0 is 3rd of 4th quadrants
csc or 1/sin > 0 is 1st of 2nd quadrants
which seems to be a conridiction to me.
OpenStudy (campbell_st):
look at 24
24 = 6 x 4
48 = 6 x 8
4 = 2^2 and 8 = 2^3
so it looks like
y = 6(2^x)
Still Need Help?
