Best ResponseYou've already chosen the best response.1the definite integral of a function between two numbers, is the area under the graph of the function between the two numbers. Ie, in your question, the definite integral you need to find is the area of the graph under f(x) between the points x= 0 and x = 28. Because your graph is essentially composed of straight lines, you can manually find the area by breaking it up into rectangles and triangles and sum the two areas together. Note, the larger (area 1) is a positive "area" (above the x axis) whereas the smaller area (area 2) is a "negative" area (under the xaxis) so when you go to "sum" them together do area 1 + ( area 2)

Best ResponseYou've already chosen the best response.1Oh, I think I get it! So just quickly looking at the graph, would the answer just be 18 then? :P @FireKat97

Best ResponseYou've already chosen the best response.1Oh right, so it'd be 32 then :p

Best ResponseYou've already chosen the best response.1So for area 1, it'd be 7x3+1/2(12x3) and area 2 as 5+2 right? @FireKat97

Best ResponseYou've already chosen the best response.1Yup, thats the basic idea. but using fractions will add accuracy :)
