D) {(-2,3),(-3,3),(-4,3)} Each member of the domain is assigned exactly one member of the range.
The domain must have only one value for y (range), unlike in the other 3 answer choices. If any section of a graph has two different y-values for the same x, then it is not a function.
According to Vieta's Formulas, if
are solutions of a given quadratic equation:
Then: is the completely factored form of
.
If choose
, then:
So, according to Vieta's formula, we can get:
But
:
