is the x^2 the denominator of everything else?
no just the denominator of 5
ok...so the last term is 5/x^2 everything else is as is..
i was thinking about rewriting it as 5x^-2, but i'm not sure
go ahead, its all good :)
8x^3 -6x +(1/2sqrt(x)) +(10/x^3) is what i get... maybe its right?
yea i got 8x^3-6x+1/2x^-1/2-10x^-3, should i substitute after this?
yep, but I think you only need the "x" value
8 -6 + (1/2) +10
yea so just substitute the x value
and youve got a typo,,,that last term should be a (+); -5(-2)=10
oh yea thanks
I get 6 as the slope... if I did it right :)
uhm i'm not sure if we're doing it right cuz the problem is actually asking me for the equation of the line
the derivative is the equation of the slope of the line; or maybe it should be in y = mx+b format?
yea i think that's what they mean y=mx+b format
y = 6x +b at (x=1,y=-5)?? -5 = 6(1) + b -5 = 6 + (-11) y = 6x-11 then
hold up, how did u get 6 as the slope, i'm up to 8-6+1/2+10
f'(x) = m 8-6=2+10=12...ahhh, I see; I multiplied by 1/2
12.5 happy :)
-5 = 12.5(1) + b -5 -12.5 = b -17.5 = b y = 12.5 - 17.5...
squeeze an "x" right up next to that 12.5
or do they want it in Ax + By = C format?
you can use the line equation to figure out a new "x value" when iterating a function solve it...
uhm not sure about that... does that mean that y=6x-11 is not it
yeah, since i miscalculated the first time with a "6", its a bad apple...toss it out before it spoils the rest :)
ok then it's 8-6+1/2+10=12+1/2=25/2
so the slope is 25/2
got it thanks :)
