POLYNOMIAL

POLYNOMIAL 函数用于计算多项式在给定点的值。

POLYNOMIAL(x 值, 系数)

x 值： 乘幂序列的输入值。 x 值是一个数字值。

系数： 系数将乘以 x 值的每个连续乘幂。系数的个数决定乘幂序列的项数。系数是一个包含数字值的集合。

注释

高阶项最先表示。系数 (a_i) 用于 x 值的连续乘幂。在以下公式中，“x”表示 x 值。POLYNOMIAL 函数使用的公式是：a₀ xⁿ + a₁ x^(n-1) + a₂ x^(n-2) + ...+ a_n

POLYNOMIAL 函数不支持任意的起始点或任意的指数间距。如果要求以上任意一项，可使用 SERIESSUM 函数。

指数是非负整数。

示例

=POLYNOMIAL(2, 9) 返回 9。

=POLYNOMIAL(2, 1) 返回 1。
