How does the graph of g(x) = x+ 5 compare with the graph of the parent
function, f(x) = x?

The function gets shifted 5 units up to form the function g(x).

Step-by-step explanation:

As the parent function is given by

And the resulting function

When a constant 'c' is added to the output of the function, the function is shifted 'c' units up.

Here, a constant '5' is added to the output of the function, so the function is shifted '5' units up.

Therefore, the function gets shifted 5 units up to form the function g(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.
