The third one is NOT true. You're welcome, hope it helps!
D. None of the above. Exponential decay implies constantly decreasing prices, i.e, f'(x) < 0 for all x.
Addition information need it like the picture
Answer: First option.
Step-by-step explanation:
1. To solve this problem you can applly the quadratic formula, which is shown below:

2. The quadratic equation is:

3. Then:
a=1
b=-4
c=-38
4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:

x=2±√42
