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.
Question

![**Exercises 59 and 60: Modeling Weight Changes**
An adult male’s weight, in kilograms, can be modeled by the function:
\[ W(t) = -\frac{2}{3}t^2 + \frac{13}{5}t + \frac{433}{5}, \quad 1 \le t \le 18 \]
where \( t \) measures months (\( t = 1 \) is January 2010, \( t = 2 \) is February 2010, etc.) and \( W \) is the male’s weight.
