5) A fish tank holds 50 gallons of water. To clean it, Jeremy has to drain the tank. The hose he uses drains the water 2 gallons each minute. The function g =50 –2m shows how many gallons of water are left g after m minutes. i Need to know the independent variable and the dependednt variable and what is the x intercept and what it means same for the y and then the domain and range and how many gallons will be left after 6 minutes?

After 6 min 38 gallons will be left. 50-2(6)=38. G is dependent ( or a function of) time. the x intercept would be when the graph crosses the x axis. So set the variable equal to zero and solve for m. which is 25. y intercept do the same thing and you get 50.

plug in zero for other variable and you will find when the function crosses the other axis.
