In this course students will learn about a variety of advanced topics in algebra. Students will expand their understanding about functions by learning about polynomial, logarithmic, and trigonometric functions. These new functions along with linear, quadratic, and exponential, will be used to model a variety of problems, including compound interest, complex numbers, growth and decay, projectile motion, and periodic phenomena.

Polynomial and rational algebra is extensively covered including advanced factoring and polynomial long division. Advanced work in probability is included that focusses on the use of conditional probability. Extensive statistics work is done to help students understand how population parameters can help to infer properties about populations. This course is aligned to the Common Core State Standards for Algebra II.

## Finding The Zeros Of Linear Functions Graphically

Zeros can be observed graphically. An x-intercept, or zero, is a property of many functions. Because the x-intercept is a point at which the function crosses the x-axis, it will have the value , where x is the zero.

All lines, with a value for the slope, will have one zero. To find the zero of a linear function, simply find the point where the line crosses the x-axis.

Zeros of linear functions: The blue line, y=\fracx+2, has a zero at the red line, y=-x+5, has a zero at . Since each line has a value for the slope, each line has exactly one zero.

## Vertical And Horizontal Lines

Vertical lines have an undefined slope, and cannot be represented in the form y=mx+b, but instead as an equation of the form x=c for a constant c, because the vertical line intersects a value on the x-axis, c. For example, the graph of the equation x=4 includes the same input value of 4 for all points on the line, but would have different output values, such as ,,,, etcetera. Vertical lines are NOT functions, however, since each input is related to more than one output.

Horizontal lines have a slope of zero and is represented by the form, y=b, where b is the y-intercept. A graph of the equation y=6 includes the same output value of 6 for all input values on the line, such as ,,,, etcetera. Horizontal lines ARE functions because the relation has the characteristic that each input is related to exactly one output.

## Reasoning With Equations And Inequalities

A.REI.D.11 Explain why the x-coordinates of the points where the graphs of the equations y = f and y = g intersect are the solutions of the equation f = g find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f and/or g are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.Modeling is best interpreted not as a collection of isolated topics but in relation to other standards. Making mathematical models is a Standard for Mathematical Practice, and specific modeling standards appear throughout the high school standards indicated by a star symbol . The star symbol sometimes appears on the heading for a group of standards in that case, it should be understood to apply to all standards in that group.
