This is all I could do for now. Hope It helps!
Answer:
Evaluate the following exponential function when x = 1.
f (x) = 9 (12)Squared X + 12
F(1) =Evaluate the following exponential function when x = 1.
f (x) = 9 (12)Squared X + 12
F(1) =Evaluate the following exponential function when x = 1.
f (x) = 9 (12)Squared X + 12
F(1) =
Step-by-step explanation:Evaluate the following exponential function when x = 1.
f (x) = 9 (12)Squared X + 12 gg
F(1) = 50
As x increases by 1 the value of f(x) doubles so we need 2^x
When x = 0 the value of f(x) = 3
The correct answer is f(x) = 3(2^x). [the top option]
For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
