WebOct 6, 2024 · The axis of symmetry is defined by x = − b 2a. If we use the quadratic formula, x = − b ± √b2 − 4ac 2a, to solve ax2 + bx + c = 0 for the x-intercepts, or zeros, we find the value of x halfway between them is … WebThe graph of a quadratic equation in the form y = ax2 + bx + c has as its axis of symmetry the line x = − b 2a . So, the equation of the axis of symmetry of the given parabola is x = − ( 5) 2 ( − 2) or x = 5 4 . Substitute x = 5 4 in the equation to find the y -coordinate of the vertex. y = − 2(5 4)2 + 5(5 4) − 1 = − 50 16 + 25 4 ...
