Find the range of f given the domain
= {-2, 0, 5, 9}

What properties allow transformation to be used as a problem solving tool

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 3 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30∘c on monday, but decreased at a constant rate in the next 3 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.

How can you tell when x and y are not directly proportional?
