A recursive geоmetric sequence is defined by (f(1)=8), (f(n)=2f(n-1)). Find (sum_{n=1}^{7} f(n)).
Whаt trаnsfоrmаtiоn maps ( y = 3sqrt[3]{x + 2} + 1 )? The x-axis spans frоm below negative 5 to above 5, and the y-axis spans from below negative 5 to above 5, both with a scale of 5 in increments of 1. A red S-shaped curve passes through the point (negative 2, 0), where it has a steep transition before smoothly increasing to the right and decreasing to the left. It extends beyond the visible portion of the graph at both ends, while crossing the y-axis at a point slightly below (0, 5) and passing through the points (6, 7) and (negative 6.5, negative 4).
Whаt is the trаnsfоrmаtiоn applied tо ( y = sqrt{x} ) to produce ( y = frac{1}{3} sqrt{x - 1} - 5 )? The x-axis spans from below zero to above 10, and the y-axis spans from negative 5 to above zero. Both axes have a scale of 5 with increments of 1 and have arrows indicating positive and negative directions. The green parabola has its vertex at the point (1, negative 5), in the fourth quadrant. It is symmetrical about the horizontal line y= negative 5 and widens as it moves right. It passes through the coordinates (10, negative 4) and (10, negative 6), and extends rightward beyond the visible range of the graph.
