It is related to econometrics, however using simple algebraic logic we can solve this problem. General formula with residual is 
, where r is a residual. Plugging the pair into the formula, we obtain that 
and r=0.5
Answer:
a = 9, b = 3
Step-by-step explanation:
The exponential function is
y = a
Find a and b by using the points it passes through
Using (0, 9 ) then
9 = a (
= 1 )
a = 9
y = 9
Using (3, 243 ) then
243 = 9b³ ( divide both sides by 9 )
27 = b³ ( take the cube root of both sides )
b = = 3
y = 9 ← exponential equation
