Answer:
y = 4
Step-by-step explanation:
For an exponential function in standard form
y = a
To find the values of a and b, use ordered pairs from the table
Using (0, 4 ), then
4 = a (
= 1 ), so
a = 4
y = 4
Using (1, 8 ), then
8 = 4 = 4b ( divide both sides by 4 )
2 = b
Thus
y = 4 ← exponential function
