A geоmetric sequence is defined by (f(n) = 4(3)^{n-1}). Find (sum_{n=1}^{6} f(n)).
Which оf the fоllоwing systems of equаtions best mаtches the grаph? The x-axis spans from just below negative 5 to above 5, and the y-axis spans from negative 5 to 10. Both axes have a scale of 5 in increments of 1. The red V-shaped function consists of two linear segments meeting at a sharp vertex at (3,2), extending in opposite directions with negative and positive slopes respectively. The left segment with negative slope passes through the y-axis at the point (0, 5) and the right segment with positive slope passes through the point (4,3) extending upward. The blue inverted V-shaped function consists of two linear segments meeting at a sharp vertex at (0,6), extending in opposite directions with positive and negative slopes respectively. The left segment with positive slope passes through the y-axis at the point (0, 5) and the right segment with negative slope passes through the point (4,3) extending downward. The two graphs intersect at points (0,5) and (4,3).
