we are asked in the problem to determine the viewing window that would allow to see the intercepts of the function y =2x2 + 35x + 75. x intercept is obtained by substituting y to zero while y intercept is obtained when x = 0. when x = 0, y =75 while when y=0, x1= 5/2 and x2=−15. the view has to contain the intercepts on the left and right and that on the top
