Course Description
This course has two sections. The first section, Quadratic Equations and Functions, involves solving quadratic equations. The 3 specific methods discussed are graphing, factoring and employing the quadratic formula. As well, characteristics of quadratic functions, such as vertex, equation of the axis of symmetry, domain, range, intercepts and maximum/minimum values are analyzed.
The second section, Logarithms, introduces the concept of logarithms as it relates to the exponential function. Both functions are illustrated on a graph as inverses of each other. Characteristics such as domain, range, intercepts and asymptotes are analyzed in terms of similarities and differences. The topic of 'change of base' is discussed. Logarithmic laws are introduced and solving logarithmic equations is explained, in relation to the solution of real world problems.
One common thread throughout both sections is understanding the meaning of a point (x,y) on a graph. There are numerous examples, where given a point on the graph, the point is substituted into the equation to find an unknown letter. Often, finding the value of the letter, leads to uncovering further information. Another common thread is understanding the meaning of the mathematical words used in the lessons. At times, lacking correct understanding of terminology can be one of the biggest stumbling blocks to new learning.
Course Goals
Upon completion of this course, students will have a solid understanding of the relationship between a quadratic equation and the graph generated by this equation. Students will discover how changing the parameters of an equation will affect the transformation of its respective graph. Students will be able to solve quadratic equations, using various methods. Students will have a strong understanding of logarithms and be able to solve problems related to logarithms.
Students will build their confidence in math.
Target Audience
This course is intended for high school students.
