Multiple Choice

A project supervisor is conducting a safety audit of a site clearing operation where a stone's trajectory is modeled by the equation h=−16t2+128t+32h = -16t^2 + 128t + 32. To verify the time at which the stone reached its peak height, which of the following is the correct mathematical setup using the axis of symmetry formula (t=−b2at = -\frac{b}{2a})?
