by hand please

2. Based on observing a histogram perhaps we decided to create the following pixel intensity mappings in order to stretch the values of a particularly compressed area (you may assume the full range is [0,255]) : [0,10][0,100](10,200](100,150](200,255](150,255] (a) (2pts) Draw a 2D graph showing these mappings. The x-axis will be the input values and the y-axis will be the output values. (b) (4pts) What are the equations for these mappings? (c) (1pt) Given a value of 50 , what will this value be mapped to? (d) (3pts) In your own words, describe the effect of this mapping
