Checkpoint 6.50. QuickCheck 1.
Which point on a parabola always lies on the axis of symmetry?
- The \(x\)-intercept
- The \(y\)-intercept
- The vertex
- The origin
Answer.
\(\text{Choice 3}\)
Solution.
The vertex
\(x\) | \(y=2x^2\) | \(y=-\frac{1}{2}x^2\) |
\(-1\) | \(2\) | \(-\dfrac{1}{2}\) |
\(0\) | \(0\) | \(0\) |
\(1\) | \(2\) | \(-\dfrac{1}{2}\) |
\(x\) | \(~~1~~\) | \(~~2~~\) | \(~~3~~\) | \(~~4~~\) | \(~~5~~\) |
\(y\) | \(\) | \(\) | \(\) | \(\) | \(\) |
\(A\) | \(\) | \(\) | \(\) | \(\) | \(\) |
\(t\) | \(0\) | \(0.5\) | \(1.0\) | \(1.5\) | \(2.0\) | \(2.5\) | \(3.0\) | \(3.5\) |
\(x\) | \(\) | \(\) | \(\) | \(\) | \(\) | \(\) | \(\) | \(\) |
\(y\) | \(\) | \(\) | \(\) | \(\) | \(\) | \(\) | \(\) | \(\) |
