F(x) = (x^2 + 3x − 4) and g (x) = (x+4) find f/g and state the domain.

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

According to the data set, where should the upper quartile line of the box plot be placed?
