Answer:
61 + 4x = y
Step-by-step explanation:
61 : starting tree height
4x : 4 times however many months pass
y : total height after x months.
Answer: Choice A. 1/64
Work Shown:
f(x) = 4^x
f(-3) = 4^(-3)
f(-3) = 1/(4^3) ... see note below
f(-3) = 1/64
Note: I'm using the rule that a^(-b) = 1/(a^b)
B :) open circle means inequality and it needs to be at least 3 so the line has to increase, meaning the arrow is going right.
