An electrician charges a base fee of $65 plus $40 for each hour of work. the minimum the electrician
charges is $145. create a table that shows the amount the electrician charges for 1,2,3, and 4 hours of work. determine the domain and range of the relation in context and explain whether or not this
represents a function.

i’ve already tried solving, as you can see, but i got this problem plz me! ☺️
