I agree with the answers to both of your questions
The only objection would be ..
for (√9,1) and (-√9,1) you should have had
(3,1) and (-3,1)
Someone verify these answers.
Thank you!
1. A biologist finds the average production in which cancerous cells are produced in rats is given by p(t)= (t^2-2t+1)/t where t is measured in hours and p(t) is measured in 1000 cells per hour. Estimate the rate at which the average production is changing at 4 hours.
It's an instantaneous rate of change
so 4 hours
I plug in the 3.99 and 4.01 in the equation (t^2-2t+1)/t
which equals to 0.937 x 1000=937?

2. State the points where f(x) = x^2 - 8 and the reciprocal of f(x) intersect.
Answer: They intersect at (√9, 1), (-√9, 1) and (-√7, -1), (√7, -1)
