Use a graphing calculator to graph f(x)=x^46x^3+11x^26x. Then use upper sums to approximate the area of the region in the first quadrant bounded by f and the xaxis using four subintervals.

The function is in the shape of a W with the middle of the W above the xaxis between x=1 and 2.
Subdivide the region into 4 subintervals and find the area using the technique you have learned in class, trapezoidal rule, Simpson's rule, integration, etc.
