Not completely sure on the symbols, but I think it is 5 x ( 22 - 9 x 2 ) - 2 ( 3 x 2 x 4 ) x 7 = 136. It doesn't really match the answers, so my advice is that you use a calculator for this one, or as the person/teacher who gave you the problem how to solve it.
Google has the complete curve of the graph. just search this- <span>y=(3x-4)(4x-3)^2 and it shows.
Hope this helps!</span>
