for 4, what do you know about the discriminant? Is there an inequality you might get from it?

#

ive tried finding the discriminant from the equation given so a=c² b=-2c-1 and c=1 but after that idk what to do

#

so for no real roots you know that b^2 - 4ac < 0
right?

yes

#

what values of that quadradic will be less then 0

#

think about the roots and how they help

#

maybe drawing it will help even more
