Approximate the area between the l-axis and the graph of f(x) = V2+2 over the interval [-1, 1] by calculating the sum of the areas of 4 rectangles with equal widths along the interval. The rectangles should be placed on the r-axis and the heights should be the function values at the left endpoint of each subinterval, as shown below. 8 5 4 3 Round to three decimal places. Area

Let f(t) = 4.32² – 7.52. Find the equation of the secant line on the graph of f() between 11 = 7 and 22 12. Write your answer in mz + b format. = y
