Hello, falloutdude!
Did you make a sketch for the second problem?
The graph looks like this:Let: . . and: .
Find an expression for whenis the area under the graph from toCode:| | (3,3) | * | *:|:* | *:::|:::* | *:::::|:::| * | *:::::::|:::| * - - * * * * - - - - + - + - - * * * * - - 0 3 x 6
The left region is a right triangle with base 3 and height 3; its area is
The right region is the area under from to
. . This is: .
Therefore: .
