Answer:
B: 3/4
Step-by-step explanation:
Since we know this is an exponential function
y= ab^x
where a is the initial value and b is the growth rate or what we multiply by
For the first point x=1 and y = 3/2
3/2 = a b^1
3/2 = a*b
For the second point x=2 and y = 9/8
9/8 = a b^2
Take the second equation over the first
9/8 = a b^2
-------------------
3/2 = a*b
3/4 = b
The growth rate is 3/4
That would also be know as the rate of change
