Let R= {0,1,2,3} be the range of h(x)=x-7. The domain of h-1(x) is?

The domain of the inverse is R

Step-by-step explanation:

Here, we want to find the domain of the inverse of the function

Mathematically, the domain of the inverse of the function is the range for the original

function

In other words, the domain of the inverse of h(x) is the range of h(x)

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
