Suppose the equation v=16.2x^2 - 192.1x + 2800 represents the value of a house from 1925 to 1950. When did the house have the lowest value? Round to the nearest whole number. (X=0 in 1925)

you will need the vertex of this parabola
the x of the vertex is -b/2a
= 192.1/32.4 = 5.929
so add 5.9 or appr 6 years to 1925 to get the year
1931
