Page 292 - Again, the occurrence of an equation of the form a = b , where a and b are unequal constants, indicates an inconsistent system.
Page 68 - Finding the Domain of a Function The domain of a function can be described explicitly or it can be implied by the expression used to define the function. The implied domain is the set of all real numbers for which the expression is defined.

Page 139 - Q(x) to obtain a quotient (polynomial of the form -Q ) plus a rational function (remainder divided by the divisor) in which the degree of the numerator is less than the degree of the denominator.
Page 325 - If the number of columns of matrix A equals the number of rows of matrix B, the two matrices are conformable and can be multiplied in the order A x B. The product A x...
Page 134 - In general, a rational function has the form where f(x) and g(x) are polynomial functions. Since division by zero is not allowed, we conclude that the domain of a rational function is the set of all real numbers except the zeros of g — that is, the roots of the equation g(x) = 0.
