Idon’t understand how to graph this (without using a calculator) i don’t know how to plot points, can someone explain how to do this?

Step-by-step explanation:

Don't let f(x) confuse you, f(x) just means y. With this they are just wanting you to randomly input an x value. I'll use the number 1, to show you an example.

f(x) = 4/x - 3

f(1) = 4/1 - 3

f(1) = 4 - 3

f(1) = 1

So for this point you would put (1,1). Which is 1 unit to the right, and 1 unit up.

Horizontal line = x values

Vertical line = y values

Hope this helps! Let me know if you need something else! :)

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

the answer is 1/4
