Based on the family the graph below belongs to, which equation could represent the graph

Second option y=log(2x)+3

Solution:

Based on the family of graphs shown in the attached file, the equation could represent the graph is y=log(2x)+3

This graph is the graph of the funtion y=log(x) stretched horizontally by a factor of 2 and translated 3 units upward.

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.
