Step-by-step explanation:

Please consider the complete question: Elaine has a business repairing home computers.She charges a base fee of $45 for each visit and $25 per hour for her labor. The total cost c(x) for a home visit and x hours of labor is modeled by the functions rule $c(x)=45+25x$.  Use the  function rule to make a table of values and a graph.

To make a table of values, we will take x values like 0, 1, 2, 3, 4 and substitute these values in our given function to find corresponding y-values as:

$c(x)=45+25x$

$c(0)=45+25(0)$

$c(0)=45$

$c(1)=45+25(1)$

$c(1)=45+25$

$c(1)=70$

$c(2)=45+25(2)$

$c(2)=45+50$

$c(2)=95$

$c(3)=45+25(3)$

$c(3)=45+75$

$c(3)=120$

$c(4)=45+25(4)$

$c(4)=45+100$

$c(4)=145$

Now, we will use points (0,45), (1,70), (2,95), (3,120) and (4,145) to graph our function. Upon graphing these points on a coordinate plane, we will get our required graph as shown in the attached file.
