\bf \cfrac{d}{dx}\left[ \cfrac{x}{11}-\cfrac{11}{x} \right]\implies 
\cfrac{d}{dx}\left[ \cfrac{x}{11} \right]-\cfrac{d}{dx}\left[\cfrac{11}{x} \right]
\\\\\\
\cfrac{1}{11}\cdot \cfrac{d}{dx}\left[x \right]-11\cdot \cfrac{d}{dx}\left[\cfrac{1}{x} \right]
\implies 
\cfrac{1}{11}\cdot 1~~-~~11\cdot \cfrac{d}{dx}[x^{-1}]
\\\\\\
\cfrac{1}{11}~~-~~11\cdot -x^{-2}\implies \cfrac{1}{11}+\cfrac{11}{x^2}
\implies 
\cfrac{x^2+121}{11x^2}

Please Help <3 Please Help <3
nadezda [96]

Hey, there! For this question, we can just start by plugging in the known values. (f + g)(x) can be rewritten as (\frac{x}{2} - 3 + 3x^2 + x - 6)(x).

Combine like terms: (\frac{x}{2} + x - 3 - 6 + 3x^2)(x)

If you add x to \frac{x}{2}, x will become \frac{2x}{2}, which means that x/2 + x = 3/2x.

--> (\frac{3}{2}x - 9 + 3x^2)(x)

If you rearrange this, then your answer will be option b. Hope this helps.

Elden [556K]
Remember
(abc)/(def)=(a/d)/(b/e)(c/f)
and
(x^m)/(x^n)=x^(m-n)
and
x^-m=1/(x^m)
group like terms
(28/12)(p^9/p^-6)(q^-5/q^7)=
(7/3)(p^15)(q^-12)=

For the given piecewise function, evaluate for the specified value of x
Gennadij [26K]

Answer:

-1

Step-by-step explanation:

For piecewise functions, you should look at the range of values and see where the number you are looking for falls. In this case, -1 is included in the domain of the middle equation, so you will be using f(x) = x

Then, all you have to do is plug in -1 for x, so f(-1) = -1
