Algebra 2 builds on the foundations of pre-algebra and algebra 1 by introducing higher grade concepts such as equations and inequalities, linear functions, systems of linear equations, matrices, quadratic equations, polynomials, and rational expressions. It also introduces more advanced graphical methods to represent and interpret data such as slope-intercept and scatter plots, and it expands upon linear functions with exponential and trigonometric functions. It also introduces more complex graphs and functions such as conic sections, circles, parabolas, and hyperbolas.

The algebra category accounts for 35%-44% of the Regents exam, making it one of the most important conceptual categories to master in order to pass the Algebra 2 Regents. Can you identify and solve a problem involving a rational exponent? Can you find the formula for a geometric sequence given an nth term? Do you understand the Remainder Theorem?

The Functions category accounts for 30%-40% of the Algebra 2 Regents. This is another one of the most important conceptual categories to master, so it's essential that you study for this section!
