Quadratic Function

To understand the concept better, let us consider an example and solve it. Let's take an example of quadratic function f(x) = 3x 2 + 4x + 7. Differentiating the function, ⇒f'(x) = 6x + 4. Equating it to zero, ⇒6x + 4 = 0. ⇒ x = -2/3. Double

Graphical Solutions of Quadratic Equations

f (x) = x 2 Quadratic functions follow the standard form: f (x) = ax 2 + bx + c If ax2 is not present, the function will be linear and not quadratic. Quadratic functions make a parabolic U-shape on a graph. If a is negative, the parabola is flipped

Quadratic Functions (examples, solutions, videos)

Examples of quadratic equations in other forms include: x (x - 2) = 4 [upon multiplying and moving the 4, becomes x² - 2x - 4 = 0] x (2x + 3) = 12 [upon multiplying and moving the 12, becomes 2x² - 3x - 12 = 0] 3x (x + 8) = -2 [upon
Quadratic Equations

Using the Quadratic Formula Just put the values of a, b and c into the Quadratic Formula, and do the calculations. Example: Solve 5x 2 + 6x + 1 = 0 Coefficients are: a = 5, b = 6, c = 1 Quadratic
