Find a power series representation for the function. (Give your power series representation centered at x = 0.)f(x) = x3x2 + 1f(

makkiz [27]

I suppose you mean

$f(x)=\dfrac{x^3}{x^2+1}$

Recall that for $|x|$ , we have

$\dfrac1{1-x}=\displaystyle\sum_{n=0}^\infty x^n$

Then

$\dfrac1{1+x^2}=\dfrac1{1-(-x^2)}=\displaystyle\sum_{n=0}^\infty(-x^2)^n=\sum_{n=0}^\infty(-1)^nx^{2n}$

which is valid for $|-x^2|=|x|^2$ , or more simply $|x|$ .

Finally,

$f(x)=\displaystyle\frac{x^3}{x^2+1}=\sum_{n=0}^\infty(-1)^nx^{2n+3}$

The value of x in this system of equations is 1.

maria [59]

Answer:

In my opinion the answer is y = 6

Step-by-step explanation:

We have two unknowns from the equation therefore, two equations are needed. These equations are:

3x + y = 9

y = –4x +10

To solve for y, we first substitute the second equation to the first one. 

3x + –4x +10= 9

x = 1

We substitute the value of x to either of the equations and solve for y. 

 

y = –4(1) +10

y = 6
