write the function in vertex form, identify the vertex,AOS, and direction of opening for y=-3x squared-10
-------
y = -3x^2-10
------
-3(x-0)^2 = y+10
--------
Vertex:: (0,-10)
------------------
AOS:: what does that mean?
-------------------
Direction: Opens downward

y = -3x^2 - 10
---
the above quadratic equation is in standard form, with a=-3, b=-10, and c=0
---
to solve the quadratic equation, by using the quadratic formula, plug this:
-3 -10 0
into this: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic vertex is a maximum at: ( -1.67, 8.33 )
---
the vertex form of the equation:
y = a(x - h)^2 + k
y = a(x + 1.67)^2 + 8.33
---
the axis of symmetry is: x = -1.67
---
the parabola opens downward (as suggested by a < 0)
