You can put this solution on YOUR website!
y = -3x^2 + 24x - 46
---
the above quadratic equation is in standard form, with a=-3, b=24, and c=-46
---
to solve the quadratic equation, plug this:
-3 24 -46
into this: https://sooeet.com/math/quadratic-equation-solver.php
---
vertex is a maximum at ( 4, 2 )
axis is x = 4
domain is all real numbers
range is all real numbers <= 2
