Question 169994: Determine wheather this statemant makes sense or does not make sense and explain your reasoning.
Because the percentage of the us population that was foreign born decreased from 1910 through 1970 and then increased after than, an equation of the form y=ax^2+bx+c, rather than a linear equation of the form y=mx+b, should model the data.

Well equations of the form of y=ax%5E2%2Bbx%2Bc where "a" is positive model parabolas that open upward.


For instance, a parabola opening upward would look like this:





Since the left side of the graph starts high, decreases, and then eventually increases, this means that a parabola would fit the data. So an equation of the form y=ax%5E2%2Bbx%2Bc should model the data.
