A translation is a movement of the graph either horizontally parallel to the \(x\)-axis or vertically parallel to the \(y\)-axis. The graph of \(y = f(x)\) where \(f(x) = x^2\) is the same as the ...

A quadratic graph is any graph which has an \(\text{x}^2\) in its equation. We draw them in a very similar way to straight-line graphs and will need to substitute values into the equation. All ...

Sufficient conditions are obtained for a function harmonic in the disk and continuous at a boundary point to have a level curve emanating from the boundary point into the disk. The one-sided ...
