求反函数 f(x)=(2-x)^2

解答

求反函数

f (x) = (2 - x)^{2}

- x + 2, x + 2

求解步骤

y = (2 - x)^{2}

用

y

替代

x

x = (2 - y)^{2}

求解

y, x = (2 - y)^{2}

- x + 2, x + 2

in v erse f (x) = \frac{x ^{\frac{1}{5}}}{8}

f (x) = 10 x^{4} - 27 x^{3} - 19 x^{2} + 42 x - 36

am pl i t u d e 3 tan (\frac{π}{2} x) + 2

d o main \frac{6 - x}{x ^{3} - 64}

cr i t i c a l 3 (x - 1)^{2}
