Multiple Choice

A technical analyst at a sports data firm is documenting the procedure for finding the peak of a volleyball serve trajectory modeled by h=βˆ’16t2+176t+4h = -16t^2 + 176t + 4. According to the model's technical specifications, which mathematical expression correctly identifies the substitution into the axis of symmetry formula (t=βˆ’b/2at = -b / 2a) to find the time the ball reaches its maximum height?
