The equation of the quadratic function that models the data is y = x^2 + 3x + 4
<h3>How to determine the scatter plot?</h3>
A quadratic function is represented as:
y = ax^2 +bx + c
Next, we enter the data values on the table to a graphing calculator.
From the graphing calculator, we have:
a = 1, b = 3 and c = 4
Substitute these values in y = ax^2 +bx + c
So, we have
y = x^2 + 3x + 4
Hence, the equation of the quadratic function that models the data is y = x^2 + 3x + 4 and the scatter plot is (a)

Answer:
Therefore, the the world's predicted population in the year 2020 is 7,911×10^6 people.
Step-by-step explanation:
Given:
P₀ = 5,642×10^6 people,
i = 1.3% = 0.013 per year,
n = 2020 - 1994 = 26 years,
We get:
Pn = P₀ e^(i.n)
. . .= 5,642×10^6×e^(0.013×26)
. . .= 7,911×10^6 people
