Question

if a->0⁺ then the roots of the equation ax²+bx+c=0 approach to(a,b,c∈R⁺)
a) -infinity to +infinity
b) -c/b to -infinity
c) -b/2a and infinity
d) imaginary numbers

Answer 1

as $a \geq 0$
if a>0
then the parabola is open upward
The discriminant can be anything
so the options 1) and 4) are correct
