For a rational function R, if the degree of the numerator isless than the degree of the denominator, then R is ________.

Find all the rational zeros of the function. x³ - 18x² + 108x - 216 O -6 0, -1 0,6 6 ±6

The time in seconds, t, it takes for a specific object being dropped from a particular height in feet above sea level, h, to reach the ground can be found by the radical function -√. At what height should you drop an object in order for it to reach the ground in 12 seconds? O 9 feet O 36 feet O 96 feet O2,304 feet

Determine the intervals on which the function is concave up or down and find the points of inflection. f(x) = 6x³ - 11x² + 1 (Give your answer as a comma-separated list of points in the form (*, *). Express numbers in exact form. Use symbolic notation and fractions where needed.) points of inflection: DNE Incorrect Determine the interval on which f is concave up. (Give your answer as an interval in the form (*, *). Use the symbol ∞ for infinity, U for combining intervals, and an appropriate type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed. Enter Ø if the interval is empty. Express numbers in exact form. Use symbolic notation and fractions where needed.) XE ( + 1,00) Determine the interval on which f is concave down.
