Question 8 of 10. help me

To know if it is function, we need to check if each input value only leads to one output value.

In this graph, input values are led to just one output value, so the correct answer is [ Yes, because each x-value has exactly on corresponding y-value ]

We can also check the vertical line test. The line doesn't pass through more then once which proves out answer.

Best of Luck!

C yes, because each x value has exactly one corresponding y value

Step-by-step explanation:

This is a function,  each x value goes to only one y value.  This is a one to one correspondence.  We can also tell by the vertical line test.  The graph only passes once through a vertical line, which makes it a function.

step-by-step explanation:

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.
