Let's consider a code example showing what would be allowed (or not) using different levels of inheritance: 1  class BaseClass {}; void freeStandingFunction(BaseClass* b); class DerivedProtected : protected BaseClass { DerivedProtected() { freeStandingFunction(this); // Allowed } };
Definition of Horizontal Axis. Horizontal means flat or level. Horizontal axis is the x-axis on a graph. The blue number line in the figure below is the x-axis, the horizontal axis.
The vertical axis on the graph is your y- axis. Your y-axis is where you plot your y-intercept, or starting point, when you are graphing. In other words, your y-axis is the up and down line on your graph. Where the red line intercepts with the two is your y-axis.
