how did they work out the lower limit of k

specifically how did they deduce the y value for which k would have 2 roots

Set the denominator =0
1+2y=0
Y=-1/2

[tulip oracle]

why the denominaator

but u can do dx/dy and flip

[austere violet]

huh

is this first year

nah a2

[austere violet]

ohhh

@tulip oracle

Vertical tangents happen when dx/dy=0

It’ll be here

So when u find Ure vertical range

Tangent *

It will be between the asymptote and that point
