Most often, we move items from one environment to another. A Ph.D rescarcher found that in doing so, dI -ACe, where t is the time in the new environment (in di its temperature T changes at a rate given by hours), C is the temperature difference (old - new) between the two environments, and k is a constant. If the temperature of the object (and the old environment) is 70°F and C=-10ʻF, what function describes the temperature T of the object 1 hours after it is moved?

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.
