Vertex … Web15 sep. 2024 · Answer: The parabola opens downward then it has a vertex point Step-by-step explanation: #Hope it helps #Carry on learning #Mark as brainliest Advertisement …
Web1 answer. Since the directrix is a vertical line of the form x=a, the parabola is vertical and opens either upward or downward. The vertex is halfway between the focus and the directrix, which is at the point (3,-4). The distance from the focus to the vertex is the same as the distance from the vertex to the directrix, which is 1. WebTransformations of the parabola Translations. We can translate the parabola vertically to produce a new parabola that is similar to the basic parabola. The function \(y=x^2+b\) has a graph which simply looks like the standard parabola with the vertex shifted \(b\) units along the \(y\)-axis. Thus the vertex is located at \((0,b)\).
Webopening downward (the maximum) is known as the vertex. An axis of symmetry can be determined by drawing a vertical line through the vertex of a parabola. This means that the equation for the axis of symmetry will be equal to the x value of the vertex. For example, if the vertex of a parabola was ( 1 , 3 ), the formula for the axis of symmetry
