Answer:
The process below should work.
Step-by-step explanation:
Let's pretend we have these two points we are trying to find an exponential equation for: (-2,6) and (2,1).
Exponential equations are of the form
where we must find
and
.
So you enter both points into that equation giving you:


I'm going to divide equation 1 by 2 because if I do the a's will cancel and I could solve or b.


By law of exponent, I can rewrite the right hand side:


Now do ^(-1/4) on both sides to solve for b:

Now we use one of the equations along with our value for b to find a:
with 

Simplify using law of exponents:

Multiply both sides by 6^(1/2) to solve for a:

with
is:

We can simplify a smidgen:

Answer:
D

to find this with your calculator
![\left[\begin{array}{ccc}5&-5&2\\1&5&-6\\1&4&-5\end{array}\right] ^{-1} \left[\begin{array}{ccc}21\\24\\21\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%26-5%262%5C%5C1%265%26-6%5C%5C1%264%26-5%5Cend%7Barray%7D%5Cright%5D%20%5E%7B-1%7D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D21%5C%5C24%5C%5C21%5Cend%7Barray%7D%5Cright%5D)
it will give you [5 -1 -4]
Answer:
x = 0.9
Step-by-step explanation:
For a problem like this, you're going to do a proportion.
