Answer:
y = 128(4.926)^x
Step-by-step explanation:
Exponential function: y = ab^x
x = 0, y = 128
128 = ab^0
128 = a
--------------------
a = 128, y = 371,293, x = 5
371,293 = 128 x b^5
b^5 = ( 371,293 / 128 )
b = (fifth root) 5^√2900.7265625
b ≈ 4.926
----------------------------------------
y = 128(4.926)^x
I hope this helps!
