FutureStarrA Standard Form Function Calculator
Just enter the number you want your calculator to work in. The calculator will automatically generate the form function for the square root, the natural logarithm, the exponential function, and the square of the exponential function. Both the positive and the negative square root, the positive and the negative natural logarithm, the positive and the negative exponential function, and the positive and the negative square of the exponential function.
Recall that the ± exists as a function of computing a square root, making both positive and negative roots solutions of the quadratic equation. The x values found through the quadratic formula are roots of the quadratic equation that represent the x values where any parabola crosses the x-axis. Furthermore, the quadratic formula also provides the axis of symmetry of the parabola. This is demonstrated by the graph provided below. Note that the quadratic formula actually has many real-world applications, such as calculating areas, projectile trajectories, and speed, among others.
Quadratic Equation. The standard form of a quadratic equation is: ax 2 + bx + c = 0. It has two roots. Solving a quadratic equation that means finding the roots. Sometimes at first complex equations are used to make it in standard form. Then values of A, B, and C are used in the formula to get the roots. The formula for finding the roots is: Write a quadratic equation in standard form with the given root(s). 7 62/87,21 Write the pattern. Since there is only one root, it is a repeated root. Replace p and q with 7. Use the FOIL method to multiply. $16:(5 x2 ± 14 x + 49 = 0 62/87,21 Write the pattern. Replace p and q with Use the FOIL method to multiply. Multiply each side by 2. $16:(5 2x2 + 9 x ± 5 = 0 62/87,21 Write the pattern ... (Source: www.tfrecipes.com)
