Answer:
B
Step-by-step explanation:
f(x) = 
=> f(x)= 
=> f(x) = 
=> f(x) = 
=> f(x) = 
Answer:
f(x) = (x - 4)² - 13
Step-by-step explanation:
f(x) = x² − 8x + 3
x² − 8x + 3 = 0
x² - 8x = -3
x² - 8x + 4² = -3 + 4²
x² - 8x + 4² = -3 + 16
x² - 8x + 4² = 13
(x - 4)² = 13
(x - 4)² - 13 = 0
The vertex form of a quadriatic function f(x) = x2 − 8x + 3 is;
f(x) = (x - 4)² - 13

You're starting at 400. Each time you're cutting in half.
So the common ratio is 1/2 which means the equation is

which is in the geometric sequence format. So the answer is choice D

Step-by-step explanation:
answer B
since for all real positive r, r^x >0
The unique function who give a negative answer is f(x)=-3* 2^x
