2025HSCQ11 (b)The graph of a quadratic function represented by the equation h=t2−8t+12h=t^2-8t+12h=t2−8t+12 is shown. The graph shows h=12h=12h=12 when t=0t=0t=0. What is the other value of ttt for which h=12h=12h=12? [Visual: A graph of the parabola h=t2−8t+12h=t^2-8t+12h=t2−8t+12, with hhh on the vertical axis and ttt on the horizontal axis.
