The answer to two down in the Nov. 11 New York Times Mini Crossword is “XAXIS.” A typical two-dimensional graph has two axes: the x-axis (horizontal) and the y-axis (vertical). The x-axis runs ...

The graph of \(y = x^2 + x − 6 \) crosses the \(x\)-axis at \(x = -3\) and \(x = 2\). The coefficient of \(x^2\) is positive, so the graph will be a positive U-shaped curve with a turning point ...

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 \(f(x) = x^2\) is the same as the graph of \(y = x^2\).
