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\)?
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.
Writing Equations of Parabolas Date_____ Period____ Use the information provided to write the vertex form equation of each parabola. 1) Vertex at origin, Focus: (0, − 1 32) y = −8x2 2) Vertex at origin, Focus: (0, 1 8) y = 2x2 3) Vertex at origin, Directrix: y = 1 4 y = −x2 4) Vertex at origin, Directrix: y = − 1 8 y = 2x2
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.
Use a system of equations to find the equation of the parabola y = ax2 + bx + c that passes through the points. Solve the system using matrices. Use a graphing utility to verify your result.
