can you please help me to solve this?

5 Let b 75 1 and consider the integral / (6:1: 9) do: where b is some real number. 1 (a) What value of b will make this integral equal to 0? (b) Sketch a graph of y = 6:1: 9 on the interval from :1: = 1 to a: = b to verify your answer in (a). Make sure to clearly label your axes and values of your graph
