16 Νοε 2022 · For problems 8 – 10 convert the following equations into the form y = a(x −h)2 +k y = a (x − h) 2 + k. Here is a set of practice problems to accompany the Parabolas section of the Common Graphs chapter of the notes for Paul Dawkins Algebra course at Lamar University.
Questions and Problems. Find the x and y intercepts, the vertex and the axis of symmetry of the parabola with equation \ ( y = - x^2 + 2 x + 3 \)? What are the points of intersection of the line with equation \ ( 2x + 3y = 7 \) and the parabola with equation \ ( y = - 2 x^2 + 2 x + 5\)?
Exercises - Parabolas. Write each quadratic function in the form y = a(x − h)2 + k y = a (x − h) 2 + k and sketch its graph. Identify the vertex, axis of symmetry, y y -intercept, x x -intercepts, and direction of opening (up or down) of each parabola, then sketch the graph.
We will learn how to solve different types of problems on parabola. 1. Find the vertex, focus, directrix, axis and latusrectum of the parabola y \(^{2}\) - 4x - 4y = 0. Solution: The given equation of the parabola is y\(^{2}\) - 4x - 4y = 0. ⇒ y\(^{2}\) - 4y = 4x. ⇒ y\(^{2}\) - 4y + 4 = 4x + 4, (Adding 4 on both sides)
For the following exercises, write the equation of the parabola using the given information. 30. Focus at (-4,0) ; directrix is \(x=4\) 31. Focus at \(\left(2, \frac{9}{8}\right) ;\) directrix is \(y=\frac{7}{8}\) 32. A cable TV receiving dish is the shape of a paraboloid of revolution.
