MTH 095 Intermediate Algebra
Lecture Hours: 4
Credits: 4
Introduces the study of functions with a focus on linear (including arithmetic sequences), quadratic (including an introduction to complex numbers), and exponential functions (including geometric sequences). Also covers converting rates using dimensional analysis. Uses a variety of methods including logarithms to solve equations. Explores topics using a graphing calculator (required) as well as traditional approaches.
Prerequisite: Placement into MTH 095 or higher; or completion of MTH 070 with a grade of C or better, or equivalent course as determined by instructor; or consent of instructor.
Student Learning Outcomes:
- Use mathematical problem-solving techniques involving constant, linear quadratic, power, and exponential functions.
- Create algebraic models of real situations using constant, linear, quadratic, power, and exponential functions.
- Use inductive reasoning to develop mathematical conjectures involving constant, linear, quadratic, power, and exponential functions. Use deductive reasoning to verify conjectures and to apply mathematical theorems.
- Make mathematical connections to, and solve problems from, other disciplines involving constant, linear, quadratic, power, and exponential functions.
- Use oral and written skills to individually and collaboratively communicate about applications involving constant, linear, quadratic, power, and exponential functions.
- Use appropriate technology to solve mathematical problems and to enhance mathematical thinking and understanding of constant, linear, quadratic power, and exponential functions.
Statewide General Education Outcomes
- Use appropriate mathematics to solve problems.
- Recognize which mathematical concepts are applicable to a scenario, apply appropriate mathematics and technology in its analysis, and then accurately interpret, validate, and communicate the results.
