Answer:
Option a. No; the domain values are at regular intervals and the range values have a common sum 1.
Explanation:
x1=3, x2=1, x3=-1, x4=-3
y1=1, y2=2, y3=3, y4=4
x1-x2=3-1→x1-x2=2
y2-y1=2-1→y2-y1=1
x2-x3=1-(-1)=1+1→x2-x3=2
y3-y2=3-2→y3-y2=1
x3-x4=-1-(-3)=-1+3→x3-x4=2
y4-y3=4-3→y4-y3=1
The data doesn't show an exponential function, because the domain values are at regular intervals and the range values have a common sum 1.
