I’m pretty sure this is how you do these kinds of questions, but I may be entirely wrong, so don’t 100% trust me on this one
First week : -1.9 + 3.5 = 1.6
2nd week : -2.4
original water level had an increase of 1.6 inches
new water level has a decrease of -2.4 inches
The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.
<h3>How to solve an
exponential function</h3>
Let y represent the population after x years.
Given that the growth rate is 4.5% per year and the current population is 1500.
Hence a = 1500, b = 100% + 4.5% = 104.5% = 1.045
y = 1500(1.045)ˣ
After 6 years:
y = 1500(1.045)⁶ = 1953
The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.

To find th vertex use the formula -b/2(a) so it's -8/2(1) so it's -4. Plug in the -4 into the original equation -4^2+8(-4)+3
16-32+3
-13
The vertex is (-4,-13)
It's minimum because the first coefficient is positive which means the parabola open up like a giant U and when plotted the vertex is a negative.
