What is the equation of a parabola with a vertex of (1, -4) and which passes through (-2 , -1)? What is the vertex form of a parabola? What is a in the vertex form of a parabola? What is x in the vertex form of a parabola?
In geometry, a parabola is a two-dimensional, mirror-symmetrical curve, which is modeled by a quadratic equation. Any point, line or object reflecting upon itself in a parabolic fashion is said to be its axis of symmetry. The latus rectum of a parabola is the chord of the parabola that ...

the perimeter of the region is 10π+20.(b) The x-intercepts of the parabola with equation y=10(x+2)(x−5) are −2 and 5.Since the line segment, PQ, joining these points is horizontal, then its length is the difference in the intercepts, or 5−(−2)=7.(c) The slope ...
Intercept Form of a Parabola:In mathematics, a parabola is the graph of a quadratic equation that either takes on the shape of a U or an upside down U. There are a few different ways to represent the equation of a parabola, and one such way is the intercept form of the parabola, ...
The Vertex formula of a parabola is used to find the coordinates of the point where the parabola crosses its axis of symmetry. The vertex is the point (h,k). As we know the standard equation of a parabola is y = ax2+bx+c. If the coefficient x2is positive then the vertex is the...

If a body starts form rest and moves along a straight line with a uniform acceleration a, then the diplacement (x) of the body in time (t) is x =1/2 at^(2) which is an equation of a parabola. Thus the displacement-time graph for a body moving with co
Normally a quadratic equation will graph out into a parabola. The standard form is f(x)=a(x-h)2+k
Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (...
