Question

which of these shows slowing, but not declining growth?

Explanation:

A curve that first rises and then its rate of increase slows (like a concave - down curve) represents slowing but not declining growth. The left graph (the curved one) shows growth that is slowing as the slope of the curve is decreasing (becoming less steep) but the value is still increasing. The right graph (the triangular - shaped one) shows a linear increase and then a linear decrease, so it has a period of declining growth. So the left graph is the one that shows slowing, but not declining growth.

Answer:

The graph on the Left
