How do you find the x-coordinate of the vertex #f(x) = -5x^2 + 2#? Algebra Quadratic Equations and Functions Quadratic Functions and Their Graphs 1 Answer VinÃcius Ferraz Jul 7, 2015 #0# Explanation: #y = ax^2 + bx + c# #a = -5, b = 0, c = 2# #x_V = -b / (2a) = 0 / 10# Answer link Related questions What are the important features of the graphs of quadratic functions?
