Finding the intercepts of a parabola let y 0.

Find x intercept calculator parabola. If the major axis is parallel to the x axis interchange x and y during your calculation. Tap for more steps. If a 0 parabola is upward a 0 parabola is downward. A parabola can have either 2 1 or zero real x intercepts.

This calculator will find either the equation of the parabola from the given parameters or the axis of symmetry eccentricity latus rectum length of the latus rectum focus vertex directrix focal parameter x intercepts y intercepts of the entered parabola. Quadratic function has the form f x ax 2 bx c where a b and c are numbers. I hope that this was helpful. Parabola equation and graph with major axis parallel to y axis.

Now we will find the x intercepts of the parabola with equation y x2 4x 3. I will explain these steps in following examples. By using this website you agree to our cookie policy. To find the x intercept s substitute in for and solve for.

To find the x and y coordinates h and k respectively of the vertex of a parabola. To graph a parabola visit the parabola grapher choose the implicit option. Since the equation for a parabola describe a quadratic function y ax 2 bx c where a b and c are any real numbers such that a ne 0 we can find the x intercepts by solving the quadratic equation ax 2 bx c 0. Graph of a parabola with x points a and b and y point c intercepts and the vertex v.

Add to both sides of the equation. A parabola can have either 2 1 or zero real x intercepts. This quadratic does not factor so we use the quadratic formula. The x intercepts are 1 0 and 3 0.
