Hi there!

f(x) = 2(1/5)ˣ
Recall the form of an exponential function:
f(x) = a(b)ˣ where:
a = initial value
b = rate of decay/growth
If b > 1, the function is undergoing exponential growth. If b < 1, then the function is undergoing exponential decay.
1/5 < 1, so the function is undergoing exponential decay, not growth.
Answer:
1. y is dependent
x is independent
2. y=64x+0
4. 64*5=320
5. 128= d(2)
d =128/2
d=64 miles per hour
6. 6.25
400/64 = 25/4
25/4 = 24/4+1/4
6.25 hours
