Question
Hand draw a tangent line to the graph at each x-component given below. Use these tangent lines to estimate the value of each derivative. Write your estimate beside each question. Using your estimates from part (a), draw the graph of f (x) on the same set of axes given above. Please use a different color of ink from your tangent lines. Shown is the graph of the population function P(t) for yeast cells in a laboratory culture. Use the method above to draw the graph of P (t) on the same set of axes given. What does P (t) represent? Describe how the rate of population increase varies over time. When is this rate highest?Explanation / Answer
f'(-3)= 2,
f'(-2)=1,
f'(-1)=0,
f'(0)=-2,
f'(1)=0,
f'(2)=1,
f'(3)=2
ii. The rate at which the population is growing (negative means population is decreasing)
iii. As time goes on, growth slows, decreases a little bit then levels off. This happens when the population runs out of resources.
iii. 7.5 hours
