Part A: What is the y-intercept of the function and what does this tell you about the table? (4 points) Part B: What is the average rate of change of the function represented by the table between x = 1 to x = 3 months and what does the average rate represent? (4 points) Part C: What is the domain of the function represented by the table if Cathy does not put any money into the box but takes out the same amount of money from

Y-intercept = 400

I need to find out a graphing program otherwise i cant do much

I believe you r supposed to be able to just use the table

I would need the table..
anonymous
  • anonymous
ok, nm you already attached it

Are there any options? Or is this a free response question?
anonymous

Free response :,C

@taylorlee
anonymous
  • anonymous
ok, figured out some of it
anonymous
  • anonymous
first you have to find the slope
anonymous
  • anonymous
slope (m) = y2 - y1/x2 - x1
anonymous
  • anonymous
m = 2 - 1/1 - 0
anonymous
  • anonymous
m = 1/1 m = 1

anonymous
  • anonymous
sorry, that wasn't right bear with me, I haven't done this kind of prob. in a while
anonymous
  • anonymous
So the yintercet and slope are 1?
anonymous
  • anonymous
y - y1 = m(x - x1) y - 2 = m(x - 1) y - 2 = 1(x - 1) y - 2 = x - 1 y (-2 + 2) = x (-1 + 2) y = x + 1 Find the y-intercept by substituting x with 0 y = 0 + 1 y = 1
anonymous
  • anonymous
yes
anonymous
  • anonymous
y=400-80x domain is {0,1,2,3}
anonymous
  • anonymous
gods, that took forever

@Tman9876 y-intercept = where on the graph x = 0 So at x = 0...we have y = 400 right?
anonymous
  • anonymous
ok

I really need a direct answer not around the bush stuff just tell me and show me how u did it please (show ur work) thanks

dang this is hard :I sorry bro, my head is about to explode
anonymous
  • anonymous
its ok everyone keeps saying that
anonymous
  • anonymous
what school do you go to anyways?
anonymous
  • anonymous
(A) Y-Intercept = 1 (copy and paste all the work I did into the box, you don't want to get points off for not showing work) The y intercept represents where x = 0
anonymous
  • anonymous
Moving on to B
anonymous
  • anonymous
rate of change is the same as the slope, so again your answer would be 1
anonymous
  • anonymous
Average rate of change is the speed at which a variable changes over a specific period of time
anonymous
  • anonymous
Moving on to C
anonymous
  • anonymous
C doesn't look complete. Would you mind posting the entire question? :)
