Answer:
Step-by-step explanation:
Ok, so i cant really awnser all the questions on that page but a very important thing to know is that it is proportinal if the layout is y=mx. the m is usually replaced with something else though. So for that first question, its proportianal. Try your best to turn those story problems into equations and then see if it matches the y = mx equation if not, its not
Are you asking about the percent of change?if so the answer is 33.3%.
As you can see, each point on f(x) is moved up 4 units to get to g(x), so the function is g(x) = f(x) + 4. The f(x) function cannot possibly be f(x)=1/2, though, because that would be a horizontal line through y = 1/2 and that function is clearly not a horizontal line. So whatever f(x) is REALLY, add 4 to the tail end of it to show its translation.
