Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ b }{ 2a }\] use this formula to find xcoordinate of the vertex then substitute all x's for its value into f(x) equation to find ycoordinate of the vertex

Best ResponseYou've already chosen the best response.0There are two ways to find the vertex.. and since your equation is already in standard form, using \(\large \frac{b}{2a} \) would be easier. unless you want to complete the square and use @triciaal 's way

Best ResponseYou've already chosen the best response.0Well, Look at the formula, ax^2 How many x^2 numbers do you have in your equation? bx How many numbers do you have that have x? and c, your only remaing number.
