Extracted text: Approximate the area under the graph of f(x) = 0.02x“ – 1.69x² + 77 over the interval [4,12] by dividing the interval into 4 subintervals. Use the left endpoint of each subinterval. The area under the graph of f(x) = 0.02x* – 1.69x + 77 over the interval [4,12] is approximately (Simplify your answer. Type an integer or a decimal.)
