Answer:

y =-14

Step-by-step explanation:

Inverse variation is of the form

xy = k where k is a constant

(-7)(-8) = k

56 = k

The equation is

xy = 56

Let x = -4

(-4)y = 56

y = 56/-4

y =-14

I guess the function is

$f(x)=\dfrac6{(1-x)^2}$

Rather than computing derivatives of $f$ , recall that for $|x|$ , we have

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

Notice that

$g'(x)=\dfrac1{(1-x)^2}$

so that $f(x)=6g'(x)$ . Then

$f(x)=6\displaystyle\sum_{n=0}^\infty nx^{n-1}=6\sum_{n=1}^\infty nx^{n-1}=6\sum_{n=0}^\infty(n+1)x^n$

also valid only for $|x|$ , so that the radius of convergence is 1.
