Analyze transformations of quadratic and absolute-value functions and identify even/odd functions.
Interpret a transformed quadratic or absolute-value function in context
Problem
Interpret \(h(t)=-16(t-2)^{2}+80\) for projectile height in feet at \(t\) seconds from launch through landing. Identify the vertex with units, use the coefficient sign to classify the extremum, verify its time lies in the motion domain, and state the physical meaning of \(-16\).
Big Picture
What this problem is really about
The vertex coordinates must be interpreted in the model’s input and output units before classifying the feature. We’ll use the coefficient’s sign to decide whether the vertex is a peak or valley, check its time against the flight domain, and distinguish the quadratic coefficient from the full constant acceleration.
