graphs question 2
1. Determine the number of times the graphs of f(x)=2^x34^x+1 and g(x)3^x2 =intersect for x between 5 and 5. Enter your answer as a simple number such as 0, 1, 2 etc.
(Hint: Graph both functions by placing one of them in Y1 and the other in Y2.)
2. A breeding group of beavers is introduced into a protected area. After t years the number of beavers in the area is modeled by the function
1. How many beavers were initially introduced?
2. Estimate the number of beavers after 5 years.
3. Determine the change in the beaver population between t = 5 and t = 10.
(Note: All answers are whole numbers.)
1.
2.
3.

f(x)=2^x34^x+1 and g(x)3^x2
First, I need to clarify what the functions are. It is hard to tell what you've got here.
Is that and ?

A breeding group of beavers is introduced into a protected area. After t years the number of beavers in the area is modeled by the function N(t)= 54/0.35+0.68t
1. How many beavers were initially introduced? Mr F says: Substitute t = 0. 2. Estimate the number of beavers after 5 years. Mr F says: Substitute t = 5. 3. Determine the change in the beaver population between t = 5 and t = 10. (Note: All answers are whole numbers.) Mr F says: Calculate N(10)  N(5). N(5) has been found from part 2. 1. 2. 3.
In the beaver question you are substituting values of t into the rule. Use your calculator to get the value of N.
