Well I don't have a fancy calculator to do your graphing. But number 6 A and B i can help with. A is just a combination of multiplying and adding and subtracting. I got the answers (A) x= -7. (B) x= -6. If you need help with the others if the other person didn't help you let me know. I do online high school so I'm always on...just new to brainly.
To do these problems, plug in a couple of values into the equations, and see the general shape of the graph. To ensure you were right, check them on an online graphing calculator. I highly recommend Desmos Graphing Calculator. Cheers!
