Question

What is the vertex of the graph of y = 3x^2 + 2x + 1?

Answer 1

formula to find x-coordinate of vertex \[\huge\rm x= \frac{ -b }{ 2a }\]

Answer 2

You're reading my mind @Nnesha ! :D

Answer 3

then substitute x by x-coordinate to find y

Answer 4

\(\bf \textit{vertex of a parabola}\\ \quad \\
y = {\color{red}{ 3}}x^2{\color{blue}{ +2}}x{\color{green}{ +1}}\qquad

\left(-\cfrac{{\color{blue}{ b}}}{2{\color{red}{ a}}}\quad ,\quad {\color{green}{ c}}-\cfrac{{\color{blue}{ b}}^2}{4{\color{red}{ a}}}\right)\)
