Create a real-life situation that fits into the equation (x+3)(x-5)=0 and express the situation as the same equation.
----------------------
Graph the function f(x) = (x+3)(x-5) just to see what it looks like.

-------------------
Let "y" be "amount of money in the bank.
Or let "y" be the height of a diver above the water.
Or let "y" be altitude of an airplane above 500' in the air.
-------------------------------
Let "x" be time.
---------------------------------
The graph shows you that y decreases from -inf to x=1.
y is negative between x= -3 and x = 5;
y increases from x=1 to inf.
y is positive after x = 5
--------------------------------------
Use that information to describe a realistic scenario modeled
by y = (x+3)(x-5)
