Determine an appropriate viewing window for the given function and use it to display its graph.
-$f ( x ) = - 0.7 x ^ { 6 } - x ^ { 5 } + 6 x ^ { 4 } - 5 x ^ { 3 } - 7 x ^ { 2 } + x - 3$

Question

The function has a wide range of values with a significant variation in the y-values. Thus, we need a wider viewing window. From the coefficients of the function, we can assume that the x-values may be in the range of -4 to 4. Therefore, a suitable viewing window would be (-4, 4) for the x-axis and (-100, 100) for the y-axis. Option C is the only graph that shows a suitable viewing window.
