A rocket is launched in the air from the ground and is 100 ft high after 1 second. After 2 seconds it is 280 ft high. Which of the following is the quadratic function that models its height h(t) after t seconds?

a...h(t)= 60t^2+40t

b.. h(t)=40t^2 + 60t

c...h(t)= 60t^2-40t

d...h(t)= 40t^2-60t

I am not looking for simply the answer. I want to you how to find it from the list provided.
