Question

.

Answer 1

i think its III.

Answer 2

I don't see how any are true.

I ) in the 1st quadrant both x and y^2 are positive so dy/dx is positive i.e. slope is positive
so I is out.

Answer 3

II x will be negative in QII and QIII. and of course y^2 is positive. so x/y^2 is neg in those quadrants. i.e. slope is negative.
so II is out .

Answer 4

oh okk tangents will be vertical at the x axis

Answer 5

slope = x/y^2 will be different for every (x,y) pair. if we move up (in a column) x is the same , by y changes so x/y^2 changes.
that means III is out

Answer 6

ok thank you!

Answer 7

I would say "none of the above"

Answer 8

yeah ill just do tht thanks:)
