WebA parabola is a graph of a quadratic function. Pascal stated that a parabola is a projection of a circle. Galileo explained that projectiles falling under the effect of uniform gravity follow a path called a parabolic path. ... Directrix: The line drawn parallel to the y-axis and passing through the point (-a, 0) is the directrix of the ... Webscale factor a parallel to the x-axis. So, just as replacing y with y a results in a stretch of scale factor a parallel to the y-axis, replacing x with x a results in a stretch of scale factor a parallel to the x-axis. The diagram below shows a graph y = f(x) in red (in this case f(x) = x³ – 4x), the graph y = f(2x) in blue, and the graph 1 ...

WebApr 6, 2024 · The equation of line parallel to the x-axis and intersecting the y-axis at the point (0, a) is at an equidistance of 'a' units from the x-axis. All points lying on the line parallel to the x-axis will have the same y coordinate . The slope of the line parallel to the x-axis will always be equal to zero. Solved Examples WebProblem 1. Find all points on the graph of y = x 3 - 3 x where the tangent line is parallel to the x axis (or horizontal tangent line). Solution to Problem 1: Lines that are parallel to the x axis have slope = 0. The slope of a tangent line to the graph of y = x 3 - 3 x is given by the first derivative y '. y ' = 3 x 2 - 3. houtdorp

WebHence the equation of line parallel to the y axis is x = 4. Example 2: Find the equation of line parallel to the y axis and has the same intercept as the line 3x + 5y - 15 = 0. We … WebThe standard form of a parabola with vertex[latex]\,\left(h,k\right)\,[/latex]and axis of symmetry parallel to the y-axis can be used to graph the parabola. If[latex]\,p>0,[/latex] … Web1 Answer. A line parallel to the x -axis will have slope m = 0. So you need to take the first derivative, and set it equal to zero to solve for the x values at which the slope of the tangent to your curve is zero. Using each solution x 0, find its corresponding y -coordinate (s) using your original equation. For point ( x 0, y 0) on a line, the ... houtdraadbout m16x300
