Question 3

Time: 00:00:00
The curve of a function f(x) = ax - 2 passes through (2, 6). Find f^{-1}(x)

f^{-1}(x) = \frac{x+2}{6}

f^{-1}(x) = \frac{x+2}{6}

f^{-1}(x) = \frac{x-2}{6}

f^{-1}(x) = \frac{x-2}{6}

f^{-1}(x) = \frac{x+2}{4}

f^{-1}(x) = \frac{x+2}{4}

f^{-1}(x) = \frac{x-2}{4}

f^{-1}(x) = \frac{x-2}{4}
