Explain and indicate the amount of definition and value range for the function

f(x) = (|x-5|)/(x-5) + 2 * ((|x-4|)(|x-6|))/((x-4)(x-6))

definitionsmängen fick jag till:

Df={x: x>4, x#5,6}=(4,5)U(5,6)U(6,infiniti)

Vf=?

In other words, paulaa, look at the specific intervals, 4< x< 5, 5< x< 6, and 6< x. With FernandoRevilla's suggestion, that should make it very easy.
