If you understand the definition of a mathematical function, a good way to judge it is that any line drawn parallel to the y-axis intersects with the values in the function’s curve only once. The same ...

Gaussian curves, normal curves and bell curves are synonymous. Each represents how statistical data with normal distribution plots on a graph. Normal distribution describes a particular way statistics ...

Microsoft Excel is designed to organize and interpret small and large amounts of data. Building a curved graph in Excel based on X and Y data points is fairly simple. You begin by adding the data ...

Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three points. A quadratic graph is a curve, so more points are plotted to support accuracy.

A quadratic graph is produced when you have an equation of the form \(y = ax^2 + bx + c\), where \(b\) and \(c\) can be zero but \(a\) cannot be zero. All quadratic graphs have a line of symmetry.
