Find equation of parabola with x intercepts
Did you know?
WebHow to Find the Equation of a Parabola? Well, we can evaluate the axis of symmetry, focus, directrix, vertex, x intercept, y intercept by using the parabola formula in the form of \( x = y^2 + bx + c \). Take any parabola equation, and find a, b, c values from equation; substitute those values in Vertex \( v(h,k) \). WebThe y-intercept is at the coordinate that has a 0 for the x-coordinate. X is 0 here and y is -3. X is 0 and y is -3. This was actually one of the points, or one of the pairs that we first tried out. You can validate that 6, 0 satisfies this equation right over here. If x is 6, 1/2 x 6 is 3, -3 is indeed equal to 0.
WebSep 10, 2024 · In this graph of the equation y = -1/2(x - 0)(x - 4), the x-intercepts are 0 and 4. In this case, since the a value is -1/2, the graph opens down and the vertex is a maximum. Lesson Summary WebSince the solutions of the equations give the x-intercepts of the graphs, the number of x-intercepts is the same as the number of solutions. Previously, we used the discriminant …

WebFeb 19, 2024 · A quadratic equation has two solutions, which means a line written in this form is a parabola and will have two x-intercepts. For example, the ... Article Summary X. To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x. You can also use the graph of the line to find the x intercept.
WebFind the equation of the parabola whose graph is shown below. Solution to Example 1 The graph has two x intercepts at x = − 1 and x = 2. Hence the equation of the parabola may be written as y = a(x + 1)(x − 2) We now …
WebOct 6, 2024 · To do this, set y = 0 and solve for x. x + 3 = 0 or x − 1 = 0 x = − 3 x = 1. Here when y = 0, we obtain two solutions. There are two x -intercepts, (−3, 0) and (1, 0).
