Enter the correct answer in the box. What is the standard form of function f?
f(x) = 4(x + 6)^2+ 5

Substitute numerical values into the equation for a, b, and c.

F(x) = ax^2 + bx + c

f(x) = 4x² + 48x + 149

Step-by-step explanation:

f(x) = 4(x + 6)^2+ 5           Distribute

f(x) = 4x² + 48x + 144 + 5               Combine like terms    

f(x) = 4x² + 48x + 149

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
