I can find the vertex using a simple formula derived from this standard form The x coordinate of the vertex is found using x frac b 2a and once I have this x value I can substitute it back into the function to find the y coordinate of the vertex completing the point h k The easiest way to find the vertex is to use the vertex formula If your equation is in the form ax 2 bx c y you can find the x value of the vertex by using the formula x b 2a So if you re working with the
We know we can find the x intercepts of the parabola by using the quadratic formula 1st x intercept x b sqrt b 2 4ac 2a 2nd x intercept x b sqrt b 2 4ac 2a The x value of the vertex is located midway between these 2 points If you average the two x intercepts you get their midpoint Y a x h 2 k is the vertex form equation Now expand the square and simplify You should get y a x 2 2hx h 2 k Multiply by the coefficient of a and get y ax 2 2ahx ah 2 k This is standard form of a quadratic equation with the normal a b and c in ax 2 bx c equaling a 2ah and ah 2 k respectively
