# Quadratic equation from data points calculator

• Quadratic Equation In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as ax²+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax² term.
This calculator uses provided target function table data in the form of points {x, f(x)} to build several regression models, namely: linear regression, quadratic regression, cubic regression, power regression, logarithmic regression, hyperbolic regression, ab-exponential regression and exponential regression.

Enter any Number into this free calculator $\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }$ How it works: Just type numbers into the boxes below and the calculator will automatically calculate the equation of line in standard, point slope and slope intercept forms.

The variable m is the slope of the line and the point (x1, y1) is a known point on the line. If you know the slope of and the coordinates for one point on the line, then you could enter those values into this equation, and the equation would then define a set, or locus, of all the points on that line.

Nov 26, 2012 · Writing a Quadratic in Standard Form: y = ax2 + bx + c Given three points on the parabola, we can write the function.1. Substitute each ordered pair into y = ax2 + bx + c to get three equations in a, b, and c.2. Solve the 3-variable system to find a, b, and c.3. Write in standard form.

Substract a + c = 1 from the above equation: 4a + c = 7 1a + c = 1-----subtraction eliminate c, find a 3a = 6 a = 2; Using a = 2 in 4a + c = 7 4(2) + c = 7 8 + c = 7 c = 7 - 8 c = -1: the quadratic equation that satisfies these points: y = 2x^2 + 3x - 1: You can prove this to yourself by substituting for x and finding y for each point

A third approach defines conics as the locus (collection) of points satisfying certain geometric properties (distance from points or lines). To differentiate between quadratic relations and quadratic functions, the general equation of a quadratic function follows: y = ax2 + bx + c. The above formula, is in the shape of a parabola.

Technically, the parabola is the actual picture of the graph (shaped like a “$$\bigcup$$”), and the quadratic is the equation that represent the points on the parabola. But a lot of times we hear the words “quadratic” and “parabola” used interchangeably.

In the regression equation the Y intercept is the S 0 for the calculation of the LOD, which is now based on six analytical data points across a concentration range as opposed to three data points at a single concentration. The LOD calculated is now based on the S0 = 0.1 ppb (y-intercept = 0.1053) to produce an LOD of 0.3 ppb. The LOQ is ...

You can factor the quadratic to get (x - 1)(x + 3) = 0 and hence the roots x = 1 and x = -3 Conversely, if you have the roots x = 1 and x = -3 you can recover the quadratic equation by forming (x - 1)(x + 3) = 0. The same is true if the roots ate complex, for example suppose that the roots are 5 + 3i and 5 - 3i then the quadratic equation is
