Interpret key graph/table features of quadratic models in context.
Interpret the axis of symmetry of a quadratic model in context
Problem
Interpret the axis \(t=2\) for \(h(t)=-16(t-2)^{2}+64~\text{feet}\). State the extremum at that time, write the equal-height relation \(h(2-d)=h(2+d)\) when both times are valid, and verify it with \(t=1\) and \(t=3\).
Big Picture
What this problem is really about
The symmetry axis names the input at the vertex and pairs valid inputs that are equally far to either side. We’ll express that equal-distance relationship algebraically, verify it with the supplied times, and interpret the shared output as matching stages before and after the model’s extremum.
