Final answer:
The essential information needed to find the standard form of a parabola using a calculator is vertex and directrix.
Step-by-step explanation:
The essential information needed to find the standard form of a parabola using a calculator is vertex and directrix.
To find the standard form of a parabola, you need to know the coordinates of the vertex, which is the highest or lowest point of the parabola. You also need to know the equation of the directrix, which is a line that is equidistant to all points on the parabola.
By knowing the vertex and directrix, you can substitute these values into the standard form equation of a parabola to find the equation in standard form.
