Question 123336: The stabilization ratio (births/deaths) for south and Central America can be molded by formula y=-0.0012x^2+0.074x+2.69 where y is the number of births divided by the number of deaths in the year 1950+x. Use the formula to find the yea in which the stabilization ratio was at its maximum.

I need to find the value of at the axis of symmetry.
whatever is will be the maximum, but I only need
to answer the problem
When the equation is in the form , the value at
axis of symmetry is
The year in which the stabilization ratio is maximum is
or late in the year 1980. answer
