What is the inverse one to one function of f(x) = square root of x-2???

alexira [117]

$f(x) = \sqrt{x - 2} \\y = \sqrt{x - 2} \\y^{2} = (\sqrt{x - 2})^{2} \\y^{2} = x - 2 \\x^{2} = y - 2 \\x^{2} + 2 = y \\x^{2} + 2 = f^{-1}(x)$

Given,

y = -3x+1 (EQ1)
y = 2x-4 (EQ2)

Equate EQ1 and EQ2

EQ1 = EQ2
-3x+1 = 2x-4
-3x-2x = -4-1
x = 1

y = -3x+1
y = -3(1)+1
y = -3+1
y = -2

(1, -2)
