Question

An electrician charges (f) an initial fee of $20 and then $30 per hour. WHAT type of graph does it show.o

A) a decreasing only graph

B) an decreasing and increasing graph

C) an increasing only graph

An equation for the total fee charged would be:

20 + 30*x, where x is the number of hours worked.

With every hour worked, the total fee will increase, so this is an increasing only graph.
