Desmos Tactical Shortcut: Plot the left-hand side and right-hand side as separate equations (e.g. \( y_1 = f(x) \) and \( y_2 = g(x) \)). Click the intersection points directly to read exact coordinates.
Because the \( t^2 \) term has a negative coefficient (-16), the graph of this equation is a parabola that opens downward (like an upside-down U). The 'maximum height' is simply the peak of that parabola, which we call the vertex. Step 1: F...
