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.
