INEQUALITIES Flashcards
1
Q
for any a, b, c, element of a real number
- trichotomy
A
if a is not equal b, then a>b or a<b></b>
2
Q
- transitivity property
A
if a>b and b>c, then a>c
also, if a<b></b>
3
Q
multiplication property of inequality
A
if a>b, and c>0, then ac>bc
if a>b and c<0, then ac
4
Q
critical number is the
A
variable in a factor that would make the factor 0
5
Q
shortcuts to the solution of the equations of quadratic inequalities
the solution to ax² + bx + c >0 where A>0 depends on the discriminant D= Β²-4ac
A
- if D>0, then the solution is x>big CN
OR
x<small></small>
6
Q
