PIC FOR NEW QUESTION
OpenStudy (whpalmer4):
average rate of change of a function \(f(x)\) from \(x=a\) to \(x=b\) is \[\frac{f(b)-f(a)}{b-a}\]
OpenStudy (jekdidkdjrjrjjr):
YA IK BUT WHATS THE ANSWER TO THE PIC I JUST POSTED
OpenStudy (jekdidkdjrjrjjr):

Ya but I'm thinking its 3 but I'm not sure
OpenStudy (whpalmer4):
they gave you a function. evaluate the function at \(x=8\), what do you get?
OpenStudy (jekdidkdjrjrjjr):
I think the answer is 3 is that righy
OpenStudy (jekdidkdjrjrjjr):
Right*
OpenStudy (jekdidkdjrjrjjr):
Like I'm pretty sure

Another pic
OpenStudy (whpalmer4):

OpenStudy (jekdidkdjrjrjjr):
um idk
OpenStudy (jekdidkdjrjrjjr):
First box
OpenStudy (whpalmer4):
don't you know how to read a graph? at x=-4, what is the y value?
OpenStudy (jekdidkdjrjrjjr):
Second
OpenStudy (jekdidkdjrjrjjr):

4th
OpenStudy (jekdidkdjrjrjjr):
Math isn't my thing
OpenStudy (whpalmer4):
find the mark on the x-axis corresponding to x=-4. go up or down until you intersect the line. go to the right or left until you hit the y-axis and read the value of y.
OpenStudy (jekdidkdjrjrjjr):
dude I don't know how
OpenStudy (jekdidkdjrjrjjr):
I won't report u for telling me the answer

OpenStudy (whpalmer4):
you can't count over 4 tick marks to the left from the point where the axes cross?
OpenStudy (jekdidkdjrjrjjr):
ummm where's the axel
OpenStudy (whpalmer4):
see the line labeled x? see the line labeled y? those are the x axis and the y axis respectively. they cross at (0,0).
OpenStudy (jekdidkdjrjrjjr):
K so it's -4 that literally doesn't give me anything
OpenStudy (whpalmer4):
now go up or down until you hit the slanted line. how many ticks did you have to go?

Ya -3
OpenStudy (jekdidkdjrjrjjr):
K so the first box is the last option?
OpenStudy (jekdidkdjrjrjjr):
Tbh if someone doesn't just tell me the answer I'm skipping this one
OpenStudy (whpalmer4):
ok, that means f(-4)=-3. now we need to do the same for x=-1
OpenStudy (jekdidkdjrjrjjr):
So wait what's the first box?

C or d?
OpenStudy (whpalmer4):
I don't care about no streak in boxes, I'm telling you how to work this sort of problem. you can figure out how to answer once you know how to work it.
OpenStudy (jekdidkdjrjrjjr):
I'm not really into that
OpenStudy (jekdidkdjrjrjjr):
Wait lemme skip dis one I have like 2 more
OpenStudy (whpalmer4):
ok, and I'm not really into helping people learn against their wishes. let's call it a draw.
