We analyze the linear function to find that it has equation

. Drawing the line, we find that it
will intersect the circle at negative and positive x-coordinates.We can prove this by
substituting 
into the given equation:




Hence,

or

, so there are both positive and negative values for

.

Answer:
$654.98
Around 7.7 years
Step-by-step explanation:
Value = P × e^(rt)
= 500 × e^(0.09×3)
= 500 × e^(0.27)
= 654.9822254
Double: 500 × 2 = 1000
1000 = 500 × e^(0.09t)
e^(0.09t) = 2
Use ln both sides
0.09t × lne = ln2
t = ln2 ÷ 0.09
t = 7.70163543
