Consider this scenario: The profit of a company decreased steadily over a ten-year span. The profit depends on the number of units sold. The following ordered pairs show the number of units sold x in hundreds and the profit P in thousands of dollars over the ten-year span in the form (x, P(x)) for specific recorded years. (46, 1115), (48, 1065), (50, 1020), (52, 1055), (54, 1010) What is P(x)?
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.
