so i get 4t^3-36
when the derivative is taken
the answer isnt a point
it should look like -3.456789
that's the interval from negative three to zero. when the function is graphed it is increasing on this interval, in addition to (3, infinity), (-3, 0) is the interval where the function is increasing with the lowest value of A.
what is the value?
thats what i need along with the work shown.
an interval is from a certain x, to a greater point of x and the region of the graph selected. when you look at the graph of the t function (original) it is obvious that the function is increasing from x=3 to x=0 where A is the smallest on an increasing interval
can you please just work it out?
so whats the final answer? im confused
lol its online hw
the answer should look something like -3.456789
my math lab? lol ive done that... and hm weird. idk you can try sending me that link. maybe im reading into the question wrong.
no its mathclass.org
https://www.mathclass.org/mc/hw.aspx?WhsAcctId=a10614d4-5e55-4afb-a76f-ee3001ef3e66&classId=2161&hwId=6234&rndSeed=32456754&mode=0&noSVG=0 it probably wont let u look at it
ha ya it wont :/ sorry!
here's a graph of the function, maybe it helps you see what is going on http://www.wolframalpha.com/input/?i=f%28t%29%3Dt%5E4+-+18t%5E2+%2B81
i get the visual. i just needa know the numerical answer.
ok im slow. the answer is -3. my bad guys. my bad. lol
