## Question

###### The number of TV channels that the average U.S. home receives has been soaring in recent, years. The function $t(x)=0.16 x^{2}+0.46 x+21.36$can be used to estimate this number, where $x$ is the number of years after 1985 (Source: Nielsen Media Research, National People Meter Sample). Use this func-tion for Exercises 97 and 98.In what year did the average U.S. household receive50 channels?
