Lial Intermediate Algebra (13e)

Lial / Hornsby / McGinnis Intermediate Algebra, 13th edition (Pearson, 2019). Single-volume developmental algebra at the intermediate tier covering the linear-equations sequence, exponents and polynomial functions, factoring, rational expressions, radicals with rational exponents and complex numbers, quadratic equations and functions, inverse and exponential and logarithmic functions, conic sections, and sequences and series. Mapped via DCM's M0482 (Intermediate Algebra) source class with cross-listing into M1431 keys for the conics and sequences chapters and M1431 cross-listing for the full exp/log chapter beyond the 3 sections present in M0482 Ch 13.
