Answer:
Graph of a function on the domain negative 2, 6 and range negative 3, 4. Graph increases from negative 2, 3 until 2, 0 and from 4, negative 2.5 to 6, 4. Graph decreases from 2, 0 to 4, negative 2.5. There are x intercepts at 2, 0 and 4, negative 2.5.
Find the x-value where f attains its absolute minimum value on the closed interval from x = -2 to x = 6. Justify your answer.
Step-by-step explanation:
Answer: Plot a point at (-6,5) then just go start up. That is your graph
Step-by-step explanation:
Range is left to right so that means that the only point on the x axsis you can plot is -6 and the domain is up and down so you cant plot a point below 5
Answer:
197.2 million
Step-by-step explanation:
The appropriate exponential equation for the population is ...
p(t) = 172.0e^(0.019t)
Then we can compute for t=7.2:
p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2
7.2 minutes from now, the population will be about 197.2 million.
___
For continuous growth (or continuous compounding), the exponential formula is ...
f(t) = (value at t=0)×e^(rt)
where r is the growth rate in one unit of time, and t is the number of time periods.
(0,0) is the origin
