Looks like you are screwed good luck:)
The function that represent this exponential decay is given as y = A(0.85)ˣ
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value and b is the multiplication factor.
Given that A is the initial value, there is a decay of 15%, hence:
b = 100% - 15% = 0.85
The function that represent this exponential decay is given as y = A(0.85)ˣ

Answer: i am not sure but thanks for the points have a good day
Step-by-step explanation:
1. Since -4 doesn’t equal -2, we will use the first function. All you have to do is plug in -4 to x, and you should get
-3
2. -2=-2, so we will use the second function to get the answer of
3
3. Once again we will be using the first function, so just plug 5 into the answer to get
-7.5
Hope this helped :)
Step-by-step explanation:
Discriminant : k² - 4(12)(27) < 0
So k² - 1296 < 0, -36 < k < 36.
