Are any of my answers correct? and you don't have to but if you mind could you tell me how to get the answer to these cause i have no idea

B and c are yes while a and d are not.
a function is when every input has exactly one output which is the case for b and c since every x value cuts the graph at exactly one point

It should be a or d i’m not sure

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
