Answer:
(2,-5)
Step-by-step explanation:
The vertex form is and has vertex (h,k). Remember h is the opposite value of the value in the equation.
This means has vertex (2,-5)

The exponential equation that represents how many grams of the compound will remain after 8 hours is:
B: C=260(0.962)^8
<h3>What is an exponential function?</h3>A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour, hence the equation for the mass after t hours is given by:
After 8 hours, the amount is given by:
Hence option B is correct.
