Hi
h=-4.9t^2+180t+2 
Yes, one can use a graphing Calculator (using x in place of t)
As to sizing... 1st derivative tells us Maxmimun is at ~18 (180/9.8) which results in height of 1600+
Using -100,2000 for y-axis and -60,60 for the x - axis, one can take a look at it
{{{drawing(300,300,   -60, 60, -100, 2000,   grid(1),
graph( 300, 300, -60, 60, -100, 2000,0, -4.9x^2 + 180x + 2))}}}
