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

PLEASE HELP WILL GIVE MEDALS
Yo mention more people i can help need all 3 answers?
yes please thank you so much :D
I'm sorry I'm new I'm lost
it's alright i just need the answers and the fastest way to get them thank you for looking tho
Idk how to leave
click a different question to leave. @DVReed96 can you help/ do you know how?
im working on it
No? I can help but Idk how on this
need help asap
this is difficult to do on a computer man
ik that is why i posted it XD
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

OK...what was the question again?

I would need the table..
ok, nm you already attached it
XD
Are there any options? Or is this a free response question?
Free response :,C
ok, figured out some of it
first you have to find the slope
slope (m) = y2 - y1/x2 - x1
m = 2 - 1/1 - 0
m = 1/1 m = 1

sorry, that wasn't right bear with me, I haven't done this kind of prob. in a while
So the yintercet and slope are 1?
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
yes
y=400-80x domain is {0,1,2,3}
gods, that took forever
@Tman9876 y-intercept = where on the graph x = 0 So at x = 0...we have y = 400 right?
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

IDK
dang this is hard :I sorry bro, my head is about to explode
its ok everyone keeps saying that
what school do you go to anyways?
(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
Moving on to B
rate of change is the same as the slope, so again your answer would be 1
Average rate of change is the speed at which a variable changes over a specific period of time
Moving on to C
C doesn't look complete. Would you mind posting the entire question? :)
@tman9876 Did you get it?
