quadratic functions and equations unit test
A quadratic function is a function that can be written in the form f(x) = ax^2 + bx + c, where a, b, and c are constants with a not equal to 0.
A quadratic equation is an equation that can be written in the form ax^2 + bx + c = 0, where a, b, and c are constants with a not equal to 0.
The unit test for quadratic functions and equations may include the following topics/questions:
1. Write the quadratic function in standard form: f(x) = 3x^2 + 2x - 7.
2. Find the vertex (h, k) of the quadratic function: f(x) = -2x^2 + 4x + 5.
3. Determine the axis of symmetry for the quadratic function: f(x) = x^2 - 6x + 4.
4. Solve the quadratic equation: 2x^2 + 5x - 3 = 0.
5. Identify the discriminant of the quadratic equation: x^2 + 8x + 16 = 0.
6. Graph the quadratic function: f(x) = x^2 - 3x + 2.
7. Determine whether the given quadratic function opens upward or downward: f(x) = -3x^2 + 2x + 1.
8. Find the x-intercepts (zeros) of the quadratic function: f(x) = 2x^2 - 7x + 3.
These are just some examples of the types of questions that may be included in a quadratic functions and equations unit test. The specific questions and topics covered may vary depending on the curriculum and level of the class.
