Finding quadratic equation using given points
Weby = 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. 1 comment ( 20 votes) WebThere are multiple ways that you can graph a quadratic. 1) You can create a table of values: pick a value of "x" and calculate "y" to get points and graph the parabola. 2) If …

WebSep 5, 2024 · If you want to find the vertex of a quadratic equation, you can either use the vertex formula, or complete the square. Method 1 Using the Vertex Formula 1 Identify the values of a, b, and c. In a quadratic equation, the term = a, the term = b, and the constant term (the term without a variable) = c. WebIf 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 always x = − b 2a, the equation for the axis of symmetry. Figure 4 represents the graph of the quadratic function written in general form as y = x2 + 4x + 3.
