Question 1106793: An insurance company is using the formula y=0.009x^2 -0.90x+27 to predict the number of accidents per million driving miles (y) for drivers of different ages (x) between 16 and 70. At what age does the model predict the fewest accidents

An insurance company is using the formula y=0.009x^2 -0.90x+27 to predict the number of accidents per million driving miles (y) for drivers of different ages (x) between 16 and 70.
graph this equation
:
+graph%28+300%2C+200%2C+-20%2C+80%2C+-10%2C+40%2C+.009x%5E2-0.90x%2B27+%29+
At what age does the model predict the fewest accidents
Minimum occurs at the axis of symmetry y = -b/(2a)
y = .009x^2 - .9x + 27
therefore
y = -%28-.9%29%2F%282%2A.009%29
y = .9%2F.018
y = 50 yr old guys have the least accidents!!
