it would be the graph on the right.
Since the equation ends with +2 the line would be 2 above the x axis
If you're familiar with the quadratic equation

well,

is the x component of the vertex, in your case, the vertex is the highest point
figure out what t is at the highest point, and then substitute that back into the equation in order to determine height
x=t in this problem
no because it don’t happen to everyone
