it is the second coordinate of the vertex

2. anonymous

the first coordinate of the vertex of $y=ax^2+bx+c$ is $-\frac{b}{2a}$

3. anonymous

the second point of my vertex is -3.333 I think

4. anonymous

as a fraction it is $$-\frac{10}{3}$$ which kind of makes a crappy decimal, but yeah

5. anonymous

right yeah

-10/3 in simplest form is -3 1/3 right?

8. anonymous

mixed number I guess

9. anonymous

yes as a "mixed number" usually we eschew mixed numbers in algebra, but whatever

10. anonymous
