The function, t(x), is shown in the table below. Is t better modeled by a linear or an exponential function? t(x) -3 10 -1 7.5 1 3 2.5 5 A Exponential: as x increases by two units, t(x) decreases at a constant percent rate. B Linear: as x increases by two units, t(x) decreases at a constant rate. Linear: as x increases by two units, t(x) decreases at a constant percent rate. D Exponential: as x increases by two units, t(x) decreases at a constant rate.

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.
