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
