1. Label the following statements as L for a linear relationship or E for an exponential relationship. _____ The population of a certain city is decreasing at the rate of 17% per year._____ The price of gasoline is increasing at the rate of $0.06 per week._____ The price of a certain product is increasing at a rate of $2.30 per year._____ The value of farm land in a certain state is increasing at a rate of 4% per year.
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.
