Finding and Using a Quadratic RegresSTO Mvuu
A new hospital tracked the number of births during its
first 6 months of operation, as shown in the table.
Month Number of Births
Find a quadratic function that models the data. Round
numerical values to the nearest whole number.
f(x) =
x2 +

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
