Find the power series expansion for f(x)= 4/(x+2); x doesn't equal 2, centered at 0

suter [353]

$\dfrac4{x+2}=\dfrac2{1-\left(-\frac x2\right)}=2\displaystyle\sum_{n\ge0}\left(-\frac x2\right)^n$

which is valid for $\left|-\dfrac x2\right|$ , or $|x|$ .

F(x) = 3(3x + 4)<br> The inverse

Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

find the inverse of the function y=9x+12

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=9x+12 becomes x=9y+12.

Now, solve the equation x=9y+12 for y.

$f^{-1}$ (x) = (x-12)/9

y=(x−12)/9

Find the 9th partial sum of the geometric sequence an=43n–1.

siniylev [52]

Answer:

39364.

Step-by-step explanation:

I guess its an = 4*(3)^(n-1)

r = 3, a1 = 4 and n = 9

Sum of n terms = a1 * (r^n - 1) / (r - 1)

so S9 = 4 *(3^9 - 1) / (3 - 1)

= 4 * (19683 - 1) / 2

= 78728/2

= 39364.
