At the point (or points) where two graphs intersect ... the solution to simultaneous linear equations. Simultaneous equations where one of the graphs is quadratic and the other is a straight ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 ...

We could for example write equations such as y = a + bx + cx 2 + dx 3 Notice that the graph of the quadratic function ... 2p + 4p 2 The demand function is a linear function given by D(p) = 231 - 18p ...

In such cases a non-linear function must be used. Non-linear means the graph is not a straight line. The graph of a non-linear function is a curved line. A curved line is a line whose direction ...

This letter presents a simple graphical criterion to obtain all common quadratic Lyapunov functions for nonlinear systems contained in the convex-hull of a set of second-order linear time-invariant ...
