The answer would be D

Step-by-step explanation:

This is because all of the models on the graph show in the same place having the same middle but at different heights but not the same standard deviation.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
