/**
 * Returns the result of reflecting the given polynomial about the Y-axis, i.e.
 * perform the change of variables: p(x) <- p(-x).
 *
 * @param p a polynomial with coefficients given densely as an array of double
 * floating point numbers from highest to lowest power, e.g. `[5,-3,0]`
 * represents the polynomial `5x^2 - 3x`
 *
 * @example
 * ```typescript
 * reflectAboutYAxis([5,4,3,2,1]); //=> [5, -4, 3, -2, 1]
 * ```
