Solve It! You want to buy a sofa that was marked down by $50 before the clearance discount was applied.

The furniture store may add the 5% sales tax before applying the additional discount, or it may add the sales tax after applying the additional discount. Which way is better for you, the customer?

Take Note: Take a moment to record the function operations in your notes.

Take Note: Use the properties of function operations to match equivalent expressions.

Draggable item		Corresponding Item
(\frac{h}{g})(x)		\frac{h(x)}{g(x)}
h(x)-g(x)		(h-g)(x)
(h\cdot g)(x)		h(x)\cdot g(x)
f(x)+g(x)		(f+g)(x)
