In the given question  two models R1 and R2 are given for revenue (in millions of dollars) for a corporation. Both models are estimates of revenues from 2020 through 2025, with t= 0 corresponding to 2020. Which model projects the greater revenue? How much more total revenue does thatmodel project over the six-year period R1 =7.21 + 0.58t R2 = 7.21 +0.45t

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.
