Question

What is the equation for the line of symmetry for the graph of the function y = -4x^2 + 6x-8?

Answer 1

`\displaystyle \\ -4x^2 + 6x - 8 = 0 \\ \\ \texttt{The equation for the line of symmetry for the graph is: } \\ \\ x = (-b)/(2a) = (-6)/(-8) = (3)/(4) \\ \\ \Longrightarrow~~\texttt{The equation for the line of symmetry is: } \\ \\ \boxed{x= (3)/(4) } ~~~~~(\texttt{vertical line})`
