Graph of y = ax 2 + bx + c If the graph of the quadratic function \(y = ax^2 + bx + c \) crosses the \(x\)-axis, the values of \(x\) at the crossing points are the roots or solutions of the ...

Save guides, add subjects and pick up where you left off with your BBC account. An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x ...

In mathematics, a quadratic is a type of problem ... values are also the places at which the graph of the standard form of the equation (y = x² – x – 1) crosses the X axis, which is where ...

In a [previous post](/dotphysics/2008/09/basics-making-graphs-with-kinematics-stuff-part-ii/), I talked about how to plot kinematics data with a spread sheet and how ...
