Step-by-step explanation:
an exponential function of the form
y = a
to find a and b use ordered pairs from the table
using (0, 0.5 ) , then
0.5 = a [
= 1 ] , then
a = 0.5
so y = 0.5
using (1, 2 ) , then
2 = 0.5 = 0.5b ( divide both sides by 0.5 )
4 = b
then exponential function represented by the table is
y = 0.5
