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.
