3.1 – Linear and Quadratic Functions
Section Learning Objectives
By the time you have completed this section you should be able to:
- Solve linear and quadratic equations
- Graph linear functions and identify the equation of a specified
line
- Graph quadratic functions and identify the equation of a parabola
from
three given points, or from other equivalent information
- Use ‘completing the square’ to study specific quadratic functions
and
to prove the general formula for solutions of a quadratic equation
- Use the discriminant to determine the number of solutions of a
quadratic equation
- Locate the maximum or minimum of a quadratic function
- Recognize applied situations involving these functions and use
the above skills to solve problems arising from such situations
