Answer:
The graph of g(x) is the graph of f(x) moved down 4 units.
Step-by-step explanation:
Subtracting a function by a constant:
Subtracting a function by a constant x is the same as moving the function down x units.
In this question:


Thus, the graph of g(x) is the graph of f(x) moved down 4 units.
Marked down 20% means it is selling for 80% of the original price ( 100% - 20% = 80%)
Multiply the original price by 80%
270 x 0.80 = $216.00
