For each scenario, identify the appropriate growth model that describes how it's changing. v The number of new polio cases has been cut in half each year due to vaccination efforts The amount of pollutants in the lake has been increasing by 4 milligrams per Liter each year v Tuition is currently $2,000 a quarter has been growing by 7% a year v The number of arrests grew for several years, but now has been decreasing Submit Question
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
#> To solve these questions we need to have a few ideas about the Linear and Exponential growth model.
Linear growth :- In general we can say that the growth rate is always same no matter how long the object growing.
Exponential growth :- Here the growth rate increases in speed over time. It means that the growth rate continues to increase forever.
