A boat's value over time is given as the function f(x) and graphed below. Use A(x) = 400(b)x + 0 as the parent function. Which graph shows the boat's value decreasing at a rate of 40% per year? The graph starts on the left near the x-axis, and near the point negative 20 comma 5 curves upward to the right. The graph starts on the left near the horizontal line x equal 25, and near the point negative 20 comma 30, the graph curves upward to the right. The graph starts on the top left near the y-axis and moves downward to the right. The graph makes a sharp turn near the point 10 comma 2.5 and continues to the right along the x-axis. The graph starts on the top left near the y-axis and moves downward to the right. The graph makes a sharp turn near the point 5 comma negative 30 and continues to the right along the horizontal line x equals negative 25.
