함수 계산기
함수의 성질을 단계별로 구하세요
이 계산기는 일변수 함수의 정의역, 치역, x절편, y절편, 도함수, 적분, 점근선, 증가/감소 구간, 임계(정지)점, 극값점(최솟값과 최댓값, 국소, 상대, 절대, 전역), 오목/볼록 구간, 변곡점, 극한, 테일러 다항식 및 그래프를 찾아 줍니다. 구간을 지정할 수 있습니다. 짝/홀성도 판별됩니다.
Your input: find the properties of $$$f=x^{4} - 6 x^{2}$$$
Parity
The function is even.
Domain
$$$\left(-\infty, \infty\right)$$$
x-intercepts
$$$\left(0,0\right)$$$
$$$\left(\sqrt{6},0\right)\approx \left(2.44948974278318,0\right)$$$
$$$\left(- \sqrt{6},0\right)\approx \left(-2.44948974278318,0\right)$$$
y-intercepts
$$$\left(0,0\right)$$$
Range
$$$\left[-9, \infty\right)$$$
Critical Points
$$$\left(x, f \left(x \right)\right)=\left(- \sqrt{3},-9\right)\approx \left(-1.73205080756888,-9\right)$$$
$$$\left(x, f \left(x \right)\right)=\left(0,0\right)$$$
$$$\left(x, f \left(x \right)\right)=\left(\sqrt{3},-9\right)\approx \left(1.73205080756888,-9\right)$$$
Intervals of Increase
$$$\left(- \sqrt{3}, 0\right) \cup \left(\sqrt{3}, \infty\right)\approx \left(-1.73205080756888, 0\right) \cup \left(1.73205080756888, \infty\right)$$$
Intervals of Decrease
$$$\left(-\infty, - \sqrt{3}\right) \cup \left(0, \sqrt{3}\right)\approx \left(-\infty, -1.73205080756888\right) \cup \left(0, 1.73205080756888\right)$$$
Local Minima
$$$\left(x, f \left(x \right)\right)=\left(- \sqrt{3},-9\right)\approx \left(-1.73205080756888,-9\right)$$$
$$$\left(x, f \left(x \right)\right)=\left(\sqrt{3},-9\right)\approx \left(1.73205080756888,-9\right)$$$
Local Maxima
$$$\left(x, f \left(x \right)\right)=\left(0,0\right)$$$
Global (Absolute) Minima and Maxima
For global minima and maxima, see extrema calculator.
Inflection Points
