How do you find the equation of a parabola if you know the vertex and a point it passes through?
Use this form: y= a(x-h)² + k ; plug in the x and y coordinates of the vertex into (h,k) and then the other point coordinates into (x,y) and solve for a.
Vertex of a parabola?
The vertex of a parabola is found by using the solution of the equation -b/2a and putting it into the quadratic equation. a is the coefficient of x^2. b is the coefficient of the other x in the equation. Ex. y=2x^2+2x+1 -b/2a = -2/2(2) = -1/2 Now put -1/2 in the place of every x in the equation. y=2(-1/2)^2+2(-1/2)+1 The vertex is (-1/2, 1/2)
The only geometric objects which can be defined using the locus of points idea is a straight line circle and angle bisector?
False, other geometric objects exist which can be defined as a parrticular locus of points, such as the parabola and the hyperbola.
What is a common end point of two sides of a polygon?
Two adjacent sides of a polygon will meet at a vertex. End points of any other pairs of sides do not have a specific name.
