The graph of this function is a straight line. Plug in x=0, and x=1, and compute the corresponding y-values. Plot those two points on a graph, and draw a straight line that passes through them.
To get the total cost after 3 months, plug in x=3. You get y=45(3)+75=135+75=210.

Sahsjing is only in part sturdy. x = 0 and y and z are opposites of yet another. attempt and visualize it. in case you have 3 numbers -c, 0, and c, that's clearly an arithmetic progression sturdy? they are each and each of a similar distance away on the quantity line. Now cube -c and c. They "bounce" to a sparkling factor on the two part of 0 on the quantity line, yet as quickly as you cube 0, it keeps to be located. So, they are besides the undeniable fact that each and each of a similar distance away, offering you with yet yet another arithmetic progression.
