Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to find an axis of symmetry [title] Check the degree of your polynomial. [step] The degree (or " order ") of a polynomial is simply the largest exponent value in the expression. If the degree of your polynomial is 2 (there is no exponent larger than x), you can find the axis of symmetry using this method.

Ending1: [substeps] The radius (or universal temperature) of the polynomial was determined when it was composed (hence the pronouns " ph " and " radial ") from both sources. The true radius of a polynomial is measured in centimeters. Ending2: [title] Figure out the spot you have decided to draw. [step] If you have decided to draw the axis of symmetry, you can find the figure of symmetry from the other side of the equation. Ending3: [substeps] To calculate 1 degree of balance, you should subtract 2 degree's from 2 degree's. This is the same as pi, and is commonly traced back to the period when pi expressed the relative separation between the earth and the mercury. Ending4: If the degree of the polynomial is higher than 2, use method 2. [substeps] To illustrate, take, as an example, the polynomial 2x 2 + 3x-1.
