The function \(\displaystyle{f{{\left({x}\right)}}}={x}\frac{{\left({64}-{x}^{{2}}\right)}^{{1}}}{{2}}\) satisfies the hypotheses of Rolle's Theorem on the interval [-8,8]. Find all values of that satisfy the conclusion of the theorem.
a.) + 1, AND -1
b.) \(\displaystyle+{4}\sqrt{{{2}}}{\quad\text{and}\quad}-{4}\sqrt{{{2}}}\)
c.) \(\displaystyle{4}\sqrt{{{2}}}\)
d.) 1
My answer. The intervals do match and equal zero so Rolles theorem can work.
Second I found the derivative maybe thats where I can't solve this problem.
The derivative that I got was \(\displaystyle{64}-{x}^{{2}}+\frac{{x}}{\sqrt{{{64}-{x}^{{2}}}}}\) maybe i did wrong on the simplifying. I at least tried hopefully some one can explain as much as possible with every single step because I can figure out the algebra part.

Answer 1

Given:
underset \((x->5^+)(lim)(1/x^(4/3)-1/(x-5)^(4/3))\)
It is known that
underset \((x->a)(lim)[f(x)+-g(x)]=underset(x->a)(lim)f(x)+-underset (x->a)(lim)g(x)\)
Then above can be written as
\(=underset(x->5+)(lim)(1/x^(4/3))-underset(x->5+)(lim)(1/(x-5)^4/3)\)
Plug Limits
\((1/5^4/3)-(oo)(since,(x-5)^(4/3)>0)\)
\(-oo(since, c-oo=-oo)\)
Hence,
underset \((x->5+)(lim)(1/x^(4/3)-1/(x-5)^4/3)=-oo\)
