Answer:
y = 4
Step-by-step explanation:
An exponential function in standard form is
y = a
Use ordered pairs from the table to find a and b
Using (0, 4), then
4 = a ( note that = 1 ), so
a = 4, then
y = 4
Using (1, 8)
8 = 4 = 4b ( divide both sides by 4 )
b = 2
y = 4 ← represents the values in the table
