Question

which of these shows slowing, but not declining growth?

Explanation:

Slowing but not declining growth means the quantity is still increasing, just at a decreasing rate. In a graphical sense, the slope of the growth - curve is positive but getting less steep. The first graph (semicircle - like shape) shows a situation where the growth rate is decreasing (the curve is getting less steep) but the value is still increasing. The second graph (triangle - like shape) shows a linear growth which does not show a change in the growth rate.

Answer:

The first graph (semicircle - like shape)
