The quadratic function f(x) = 0.0041x^2 - 0.44x +36.08 models the median, or average, age, y, at which U.S. men were first married x years after 1900. in which year was this average age at a minimum?( round to nearest year). What was the average age at first marriage for that year? ( round to nearest tenth.)
So far i can only plug in the number and my equation is y=0.0041(1900)^2 - 0.44(1900) +36.08. i don't fully understand what to do. i don't know if my equation were setup right.
