A. Determine Mel
Direction: Without graphing, determine the opening of the parabola for each quadratic function
Example: f(x) = 4x?

Answer: The parabola opens upward.
1. g(x) = 3x"
2. G(x) = ½x² + 3x - 1
3. S(x) = x² - 2x - 3
4. F(x) = -x² + 4x - 1
5. y= 2x² - 2
6. h(x) = --4x² - 2x + 1
7.H(x) = -x +
8.k(x) = 2(x - 2)²
9. R(x) = (x + 2)² + 3
10. y = -2(x - 1)²​
