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.

Textbook Question

Chapter 6.3, Problem 62E

Average Monthly Temperature in Phoenix The following function approximates average monthly temperature y (in °F) in Phoenix, Arizona. Here x represents the month, where x = 1 corresponds to January, x = 2 corresponds to February, and so on. (Source: www.weather.com)

f ( x ) = 19.5 cos [ π 6 ( x − 7 ) ] + 70.5

When is the average monthly temperature (a) 70.5°F (b) 55°F?
