We are given with the data revealing about the median age of an American man marries for the first time in a specific year. In this case, we are asked to determine the average rate of change during a ten-year interval. To have a negative average rate of change, the proceeding decade's median age should be less than the number before. In this case, all of the choices lead to negative average rate of change.

Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
Can't tell what "y = (1 + x2)3" means. Which terms are exponents?
