Practice problem
Find the average rate of change of a(t)=1t+4a(t)=\dfrac{1}{t+4}a(t)=t+41 on [9,9+h][9,9+h][9,9+h].
Your answer will be expressed involving hhh.
h13(h+13)\dfrac{h}{13(h+13)}13(h+13)h
113(h+13)\dfrac{1}{13(h+13)}13(h+13)1
h13(h2+13)\dfrac{h}{13(h^2+13)}13(h2+13)h
Does not work
Type a concept, like “slope” or “photosynthesis”.
