1 answer:

4 0

$f(x)=-6x+2\to y=-6x+2\\\\\text{Interchange the y and the x}\\\\x=-6y+2\\\\\text{Solve for y}\\\\-6y+2=x\qquad|-2\\\\-6y=x-2\qquad|:(-6)\\\\y=\dfrac{x-2}{-6}\\\\y=\dfrac{2-x}{6}\\\\Answer:\ f^{-1}(x)=\dfrac{2-x}{6}$

How many solutions does the equation - 8x + 5 = - 8x + 4 have

KiRa [710]

$- 8x + 5 = - 8x + 4 \\ - 8x = - 8x + 4 - 5 \\ - 8x = - 8x - 1 \\ 0 = - 1(false)$
