Question 21166: hi.I have a question how can you find the coordinates of the vertex.Make a table of values,using x-values to the left and to the right of the vertex.
1.y=3x^2
how can we now "b" and "c" with this kind of equation.there`s no graphs sktechings.
Thank you.

You can put this solution on YOUR website!
The equation is y=3x^2+0x+0
b and c are both 0
The vertex is at (0,0)
