The graph of any quadratic equation is a parabola. A parabola will look like either a right-side-up U'': or an upside-down U.''. The places the parabola crosses the x-axis are called the x-intercepts, just like with linear equations.ince not all quadratic equations have solutions, the graph might not have any x-intercepts. It could look like this, for example: The y-intercept is the value we get when we plug x = 0 in to the equation ax 2 + bx + c. When we do that, we find. a (0) 2 + b (0) + c = c.
In computer science the term polymorphism means âa method the same as another in spelling but with different behavior.â The computer differentiates between (or among) methods depending on either the method signature (after compile) or the object reference (at run time).
Inheritance is the ability to use the data and methods of one kind of object by another as if they were defined in the other object to begin with. Polymorphism means that an object that inherits appears to be both kinds of object, the kind of object it is itself and the kind of object from which it inherits.nheritance is the ability to use the data and methods of one kind of object by another as if they were defined in the other object to begin with.
