Answer:
y = 4
Step-by-step explanation:
The form of the exponential function is y = a 
Use the given points to solve for a and b
Using (0, 4 ), then
4 = a
(
= 1 ), thus a = 4
y = 4 
Using (2, 196 ), then
196 = 4b² ( divide both sides by 4 )
49 = b² ( take the square root of both sides )
b =
= 7
y = 4
← exponential function
