Question 624022: I am having difficulty with this graphing problem because when I enter the equation i get basically a straight line graph. Do I solve the equation first by using the quadratic formula or can I just enter the equation in the graphing calculator.. If so how do I know how to size the window.
The equation is: h=-4.9t^2+180t+2 where h is the height and t is time.
Thank you

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
