Question

x=(5m/s)t+ (0.75m/s3)t3 how do u find coordinates 4 the graph o u differentiate first?

Answer 1

Do you just want to plot it? Why would you want to differentiate?

The lowest point will be x = 0 at t = 0, and it will keep rising after that.

I recommend only plotting it from t = 0 to t = 6. It rises too fast after that to be worth plotting.

Include these points, and draw a smooth line through them:
(0,0)
(1,5.75)
(2,16)
(3,35.25)
(4,38)
(5,118.75)
(6,192)
