Describes the width of the parabola
WebAug 18, 2024 · 2 Answers By Expert Tutors. The equation of the general parabola with axis parallel to the y axis and vertex at the origin is: y=x 2 /4p where (0,p) is the focus. The directrix is y=-p and the length of the latus rectum is 4p. You should be able to make the necessary substitutions. Note: What is described in the question is actually a circular ... WebYour thinking is correct, though the more traditional form of the equation is y = (x-h)^2 +k. As you noted, positive H is to the right, negative H (which shows up as y = (x+h)^2 - k where the value of h is actually positive) is to the left. Positive k is up, negative k is down. 1 comment ( 2 votes) Marcos/Freddy fazebear 2 years ago

WebIf A is greater than 1, it's going to be steeper, like this. If A is less than 1 but greater than 0, it's just going to be wider opening, like that. Actually, if A is 0, then it just turns into a flat … WebA coordinate plane. The x- and y-axes both scale by one. The graph is the function x squared minus x minus six. The function is a parabola that opens up. The vertex of the function is plotted at the point zero point five, negative six point two-five. The x-intercepts …
WebThe graph of y=(x-k)²+h is the resulting of shifting (or translating) the graph of y=x², k units to the right and h units up. For example, y=(x-3)²-4 is the result of shifting y=x² 3 units to the right and -4 units up, which is the same as 4 units down. WebIt's the maximum point. And the axis of symmetry is the line that you could reflect the parabola around, and it's symmetric. So that's the axis of symmetry. That is a reflection …

Webof the parabola is 3.0 meters and the depth of the form is 1/2 meters. How far above the center of the form will the sunlight be the most concentrated? Answer: The diameter is 3.0 meters so the radius is 1.5 meters. The point (1.5, 0.50) is on the parabolic curve, so 0.50 = a (1.5) 2 and so a = 0.22. Then the focus is at f = 1/(4x0.22) = 1.1
