When graphing y = 2x2 + 35x + 75, which viewing window would allow you to see all of the intercepts and the minimum as closely as possible?

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
