Study Notes
Quadratics
- Quadratics are equations where the highest exponent is 2.
- They form a parabolic shape.
- Quadratics can model gravity and the speed of objects.
- They're used to find optimal solutions, such as finding the best deals or maximizing profit.
Vocabulary
- Quadratic Equation: An equation where the highest exponent is 2.
- Vertex: The highest or lowest point of a parabola. It's the middle point.
- Axis of Symmetry: A line that divides the parabola perfectly in half.
- Roots/Zeros/Solutions: The x-intercepts of the parabola (where the y-value is 0).
Standard Form
- The standard form of a quadratic function is y = ax² + bx + c
- 'a' represents the vertical stretch of the parabola.
- 'c' is the y-intercept.
Maximums and Minimums
- Maximum: The highest point of the parabola occurs when 'a' is negative.
- Minimum: The lowest point of the parabola occurs when 'a' is positive.
Finding the Vertex and Axis of Symmetry
- The x-coordinate of the vertex is given by the formula: x = -b / 2a
- The y-coordinate of the vertex can be found by substituting the x-value back into the equation.
- The axis of symmetry is a vertical line passing through the vertex; its equation is x = the x-coordinate of the vertex.
Additional Practice
- Example problems show how to write quadratics in standard form and determine if there will be a min or max.
- Applying the formula to find the vertex and axis of symmetry is demonstrated with worked examples.
