Answer:
F(2b-1) = 4b² - 6b + 4
Step-by-step explanation:
Replace all the x with 2b-1
F(x) = x² - 2x + 4
F(2b-1) = (2b-1)² - 2(b) + 4
= 4b² - 4b + 1 - 2b + 4
= 4b² - 6b + 4
If we have the function:
f(x) = 6x
and translated to
g(x) = 6 (x - 5) - 7
Then, the graph of f(x) to obtain g(x) is
shifted 5 units to the right and 7 units up
The answer is the first option.
Answer:
B
Step-by-step explanation:
41 + 40 + 57.28 ft, 138.28 ft.
Given:
The function models the number of movie theaters in the United States t years after 1985.

To find:
The year in which the United States will have 35,000 movie theaters.
Solution:
We have,

Putting f(t)=35000, we get



Divide both sides by 750.


It means, United States will have 35,000 movie theaters 20 years after 1985.

Therefore, United States will have 35,000 movie theaters is 2005.
