Don't factor). b) (fg)(x) = ____ (Simplify the answer. Don't factor). ((f)/(g))(5) = ___ (Simplify the answer. Don't factor).
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.
