Answer:
2nd option
Step-by-step explanation:
given an exponential function in the form y = a
to find a and b use the coordinate points it passes through
using (0, 4 ) , then
4 = a
[
= 1 ] , that is
a = 4 , so
y = 4
using (2, 100 )
100 = 4b² ( divide both sides by 4 )
25 = b² ( take the square root of both sides )
= b , that is
b = 5
then exponential function is
y = 4 .

Step-by-step explanation:
Since the opposite sides are parallel in the given polygon, it is parallelogram.
1/2 + 1/4= 3/4
1/2 + 1/2 = 2/4
2/4+ 1/4= 3/4
