A function such as y = ax2 + bx + c is continuous. This is useful in nature, since an extended object such as a log is often partly hidden by branches, and the curve fitting to samples of the log allows occluded parts to be implied. An equation for a curve is ...
If you factor the quadratic equation, it is done through a remarkable product or a common term. It must be in the general form {eq}ax^{2}+bx+c=0. {/eq} Answer and Explanation:1 Given: {eq}y^2 - 20y + 100 = y - 10 {/eq} ...

What is Vertex Formula? The vertex formula helps to find thevertexcoordinates of a parabola. The standard form of a parabola is y = ax2+ bx + c. The vertex form of the parabola y = a(x - h)2+ k. There are two ways in which we can determine the vertex(h, k). They are: ...
to the attendees, he provides a few examples, and starts with a simple equation. He starts with the quadratic equation of ax^2 + bx + c, and points out the coefficients in the equation. First, he points out that “a” is the coefficient of x^2, and that b is the coefficient of ...
In Ax+By=C, what does everything stand for? Does the x mean the x-axis, y mean y-axis, and C mean slope? What are the x-intercept and the y-intercept of the graph of 8x - 7y = -56? What is the x-intercept of the graph 2x - 6y = 12? What is the y-intercept? If f...
is represented by the formax + b = c, ax + by + c = 0, andax + by + cz + d = 0.On the basis of the degree of the variables, elementary algebra branches out intopolynomialsand quadratic equations. Generally,quadratic equationsare represented byax2 + bx + c = 0, whereas ...
