given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.

a) 2
b) 3
c) 4
d) 5

The answer is D) 5.

Step-by-step explanation:

Pick a point on the graph, such as 6, where f(x) intersects the x-axis. Count the points up to g(x). There are 5 units from f(x) to g(x) on the graph.

to determine the unit cost your would divide the total cost by the number sold.

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
