Math Problem Statement
Solution
In the image, we are asked to determine the direction in which each parabola opens based on the equations provided. Let’s analyze each equation individually to confirm the answers:
-
Equation:
- Analysis: The coefficient of is , which is positive. When the coefficient of in a quadratic equation is positive, the parabola opens upward.
- Answer: Upward.
-
Equation:
- Analysis: The coefficient of is , which is negative. When the coefficient of is negative, the parabola opens downward.
- Answer: Downward.
-
Equation:
- Analysis: Expanding gives with a positive coefficient. Since the squared term is positive, this parabola opens upward.
- Answer: Upward.
The solutions provided in the image are correct.
