Answer:
an = -4 * (-3)^ (n-1)
513560652
Step-by-step explanation:
We can find the common ratio
12/-4 = -3
r =-3
The explicit formula is
an =a1 r^(n-1)
an = -4 * (-3)^ (n-1)
We want the 18 th term
a 18 = -4 (-3) ^ 17

Answer:
Step-by-step explanation:
The inverse function for a set of ordered pairs can be found by swapping the x- and y-coordinates in each pair.
![g^{-1}(-1)=9\qquad\text{from the $g(x)$ ordered pair $(9, -1)$}](https://tex.z-dn.net/?f=g%5E%7B-1%7D%28-1%29%3D9%5Cqquad%5Ctext%7Bfrom%20the%20%24g%28x%29%24%20ordered%20pair%20%24%289%2C%20-1%29%24%7D)

The inverse of a function expressed algebraically can be found by swapping the x- and y-variables and solving for y.
![h^{-1}(x)\qquad\text{is found from }x=h(y)\\\\x=3y+8\\x-8=3y\\\\y=\dfrac{x-8}{3}\\\\\boxed{h^{-1}(x)=\dfrac{x-8}{3}}](https://tex.z-dn.net/?f=h%5E%7B-1%7D%28x%29%5Cqquad%5Ctext%7Bis%20found%20from%20%7Dx%3Dh%28y%29%5C%5C%5C%5Cx%3D3y%2B8%5C%5Cx-8%3D3y%5C%5C%5C%5Cy%3D%5Cdfrac%7Bx-8%7D%7B3%7D%5C%5C%5C%5C%5Cboxed%7Bh%5E%7B-1%7D%28x%29%3D%5Cdfrac%7Bx-8%7D%7B3%7D%7D)
A function of its own inverse returns the original value:
![\boxed{\left(h\circ h^{-1}\right)(-1)=-1}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cleft%28h%5Ccirc%20h%5E%7B-1%7D%5Cright%29%28-1%29%3D-1%7D)
