depending on what type of calculator you use I'm not sure if I can help on that but on the ti 84 calculator hit the "y=" button (it's on the very top row of buttons) and type in your equation (to input the x hit the button directly underneath the button labeled "MODE" it should have look like "X,T,o,n") make sure to put the entire equation in one row if you have 2 equations make sure to put them in seperate rows. and dont put y= in when you type the equation just start typing it. and when all that's done hit the graph button and you should be able to see the graphed equation. or hit the blue button labeled "2nd" then hit the graph button and it will show you the domain and range and all the ordered pairs for your function.
