<h3>Quadratic functions</h3>
A quadratic function is a function that has a degree of 2. Given the quadratic function shown:
f(x) = x² + x
where
x is the total months
In order to use the function to predict the number of births for month 8, we will substitute x = 8 into the function as shown:
f(x) = x² + x
f(8) = 8² + 8
f(8) = 72 births
This shows that there will be about 72 births for month 8
