Each equation given below describes a parabola. Which statement best compares their graphs?x = 2y2 x = 8y2
Question
Each equation given below describes a parabola. Which statement best compares their graphs?
x = 2y^2
x = 8y^2
Solution
1. Break Down the Problem
We need to compare the two given equations of parabolas:
- Equation 1:
- Equation 2:
2. Relevant Concepts
The standard form of a parabola that opens to the right is given by , where is a constant that affects the width and orientation of the parabola:
- A larger value of results in a narrower parabola.
- A smaller value of leads to a wider parabola.
3. Analysis and Detail
For our equations:
- Equation 1:
- Equation 2:
Since , the second parabola (Equation 2) opens more narrowly compared to the first parabola (Equation 1).
4. Verify and Summarize
We can summarize that the parabolas open in the same direction (to the right), but the width of the parabolas is different. The parabola represented by is narrower than the one represented by .
Final Answer
The statement that best compares their graphs is: The parabola is narrower than the parabola .
